In this assignment, I will perform a two tailed test and a one tailed hypothesis test for the average difference in yields that are provided by using old and new fertilizers. The data on yields on 15 parcels of land is provided in the table below: The first part of the assignment is to perform a two tailed hypothesis test for the two independent samples given. Assume that the population of yields is normally distributed, there are no outliers in the data, the variances are homogeneous. Then, it is possible to use two-sample Student’s t-test for independent samples (" ...

For the given case, I would set null hypothesis and alternative hypothesis as following:

Null Hypothesis H0= New Fertilizer has same effect on the tomato Yield as the Old Fertilizer; μ1 = μ2. H1 = Tomato yield from New Fertilizer is higher than the old fertilizer; μ1 > μ2 It is assumed 5% level of significance. i.e. α = .05

First one tail F-test is performed which gave result as below

The test shows that there remains homogeneity in the variances of the two populations as F(14,14) =1.08 & p is equal to 0.44 which is greater than 5% indicating that assumption of different hypothesis for the same test used by farmer gave the same result.

Now, as different approach,

Assuming the null hypothesis, H0: The effect on tomato yield from ...

Part One

The farmer tested the hypothesis H0: μ1 - μ2 = 0

H1: μ1 - μ2 ≠ 0

First, the farmer must have tested for the equality of variances to determine whether the t-test that will be used will assume equal variances or not before proceeding to the t-test. In this case, the highlighted value P (F<=f) one-tail is greater than 0.05. As such, the t-test should assume equality of variances. Undertaking the analysis in Excel, the following output is obtained. The excel working apply the formulae used in manual computation to generate the outcomes as follows: Examining the t statistic computed, the value that is ...

Introduction

With the escalation in cost production and environmental concerns, researchers have in the recent past focused in investigating resourceful means of increasing yields while reducing fertilizer use. Arnall & Godsey assert that the seeding rate and hybrids that promise the highest crop populations is continuously sort by corn cost cultivators worldwide (2013). Nielsen et al. notes that the crop populations are tied to the end yields. Corn populations have greatly increased in Indiana over the past thirty years to make about 340 plants ...

The issues faced by the Indian River Lagoon is quite similar to that of many rivers, lakes, and even oceans from various locations of the world. The steady decline in the marine population of the lagoon escalated to alarming rates by the end of the last decade. A few legislations that were passed in the early nineties to limit trawling in the estuarine region and as well as the direct dumping of untreated sewage wastes, had proved effective in the past. But later into the decade, the rescue efforts to salvage the lagoon and the ecosystem associated with it, ...

Introduction

Sugarcane has been grown by human beings for many years because of its many uses. It is a perennial grass that grows well in frost-free tropical areas. The crop is mainly propagated vegetatively with 30-40 cm long fresh cuttings. The crop has a cycle of between 10-24 months modern agricultural practices have made it possible to reduce the growing period of the plant crop as well as for the ratoon crops. The current sugarcane crop is an inter-hybrid cane breed to provide high sugar content (Moore et al. 10). Originally, the plant was used for chewing, but currently, it ...

Which is a better choice at the grocery store: paper bag? Plastic bag? Or tissue bag? Explain your answer.The best choice at the grocery store is to bring a used bag. Paper bags, plastic bags, and tissue bags all have individual issues associated with their use. Paper bags come from a renewable source, and are biodegradable. Despite this, they require more energy to make and are less likely to be reused. Plastic bags are not biodegradable but consume less energy to be made than paper or tissue bags. Tissue bags are the highest energy consumptive option, but are more ...

Abstract

In most parts of the Arab countries, the limited resources of water pose adverse constraints to both the social and economic development, while also threatening the people’s livelihood. The available surface water keeps on declining, and the ground water over-pumping that goes beyond the natural recharge rates has continued to cause great negative impact in the lowering of water table. Over-pumping of ground water also increases ground water salinity, ground water depletion, and ecological degradation (SCENR 5). The outcome prompted the Qatar government to start regulating its water resources as a measure ...

An explosion at a fertilizer manufacturing plant in the Western part of Texas that occurred in early 2013 killed 15 people and injured 180 more. The explosion leveled buildings within a five block radius and the instruments at the Geological Survey of the United States recorded a 2.1 magnitude earthquake. The explosion was caused by the reagents used as raw materials for fertilizer manufacturing. Inorganic fertilizer is manufactured from chemical substances such as ammonium nitrate and anhydrous ammonia, which had been stocked at the West plant during the explosion. This paper explores the cause of the explosion, the chemical ...

Abstract Global warming is no doubt the the greatest and most far reaching societal and professional long term threat to every end of human livelihood. Agriculture is quickly growing into one of the biggest producers of greenhouse gases. And therefore, global warming. The recent development of industrial farming has exasperated the amount of methane and nitrous oxide gases being released into the atmosphere. This has been done under the pressure of many different stimuli, including government lobbyists and stimuli, and companies like Monsanto. Indifference and lack of public education has ensured that this remains a problem for the immediate ...

Many plants hold the capacity to uptake and absorb different chemicals and substances from the soil. Since the world has gone through and is currently going through vigorous industrialization, the chemical waste of factories and other chemicals is usually disposed of into water bodies. If plants are allowed to grow or flourish in these areas, then they are able to uptake many of the chemicals and then either these plants can be harvested, disposed of and they can help to clean up the environment and make it safer. The biggest benefit of Phytoremediation is that it is a low-cost ...

ABSTRACT

The research argues that although a gas flaring stoppage is not successfully in-place in Nigeria, fitting the appropriate technology with complementary economic and institutional factors can lead to near-zero or zero gas flaring. Nigeria is a developing country with a unique culture of many tribes and one of the largest growing urban populations in the world. Infrastructural, political and economical challenges to meeting the goal are introduced. Reinjection of gas back into wells is not available as an option to gas flaring because a large region for gas production is wetlands (Buzcu-Guven et al. 2012). Wetlands ...

Introduction

Arable soil can be described as soil tilled or ploughed regularly, usually under a crop rotation system. It is also an agricultural soil that is filled by crops sown as well as harvested in a similar agricultural year, at times over one time. Soil can as well be regarded as arable if it is utilized as temporary hayfields for pasture or mowing, kitchen and market gardens, and temporary fallow land. This means that this kind of soil is not sown for one or more seasons of growing, but it is not left to lie idle for over five years. Arable soil ...

An externality denotes a situation in which a third party not involved within a transaction incurs a benefit or cost (Amacher & Pate, 2013). That is, an externality occurs whenever a third party experiences side effects in a transaction between sellers and buyers. Whenever a third party gains from the transaction, it is termed a positive externality.

On the contrary, whenever a third party experiences a cost or loss it is referred to as negative externality (Amacher & Pate, 2013). For instance, a new fertilizer plant producing fertilizer for export also inflicts environmental air pollution. Residents of the area experience bad air quality due to air pollution, thus, a negative externality. ...

In his book the jungle, Sinclair’s s main concern was not to the meat but to the workers who produced. It was then that he said that. ‘I aimed at the public’s heart and by accident hit its stomach’. He attempted to make the public aware that the life of an immigrant was very hard in the 1800s. In real sense, he did not actually assist people to know the harsh condition s but the bad meat that they were eating. This is what hit their metaphorical stomachs (Sinclair, 2006 p. 18).

Does the addition of fertilizer increase crop production? Farmers are very interested in the amount of fertilizer used versus how much yield a crop can give. Fertilizer costs money and determining the amount of fertilizer that will maximize production is very important. My hypothesis is that the addition of fertilizer will increase crop yield.

I predict with the addition of more fertilizer, the production of corn will increase. The dependent variable is tons of corn produced in an acre field. The independent variable is the addition of fertilizer to the field. There will be experimental plots (each with differing levels ...

Introduction

Pollution of the environment is one of the oldest problems in the history of civilization. Man has long been considered the environment primarily as a source of resources, seeking to achieve independence from it, to improve the conditions of its existence. While population and the scale of production was small, and very extensive natural spaces, to achieve the goals we were willing to sacrifice some of the untouched nature, exactly as some degree of purity and water. This process in our relatively closed, not unlimited world cannot continue indefinitely. For example, it is estimated that each year for every person ...

Water can be considered one of the most vital resources in the planet because of its benefits to every aspect of life. Aside from being used for drinking, water ensures that life is continously sustained around the planet. However, as mankind continues to grow, supplies of critical resources like water are slowly drying out due to various causes. While a majority could argue that it is due to the changing climates causing extreme heat, there are others saying that the reducing supply for water is because of pollution. For countries like the United States, issues regarding water supply and pollution ...

Abstract

Solid waste and wastewater are primary sources of pollution from food processing industries. The wastewaters usually contain high suspended solids, organic starch and sugars that may contain toxic substances to the environment. Solid wastes come from organic materials while the mechanical preparation processes need biological treatment before releases into the environment. When untreated, they find their way into other water plants like lakes and streams. Since they have higher nutrient content, they result of eutrophication of the water systems hence causing algal growth. It, therefore, compromises the stability of the aquatic ecosystems as the water quality is changed. It ...

Introduction

As defined by the Brundtland Commission, sustainability is a "development that meets the needs of the present without compromising the ability of future generations to meet their own needs" (EPA 2014). Food production and consumption patterns and trends are one of the main contributing factors to environment pollution today. In the event of a growing global population and demographic change, the sustainability issues arising out of the food system are likely to turn more serious in the near future. It is expected that the economic prosperity and the growth of population will increase the demand for food beyond the natural capacity, ...

Raphanus savitus is a cool-season crop. The radish seeds are living organisms that lie in the state of dormancy and affected by different factors such as air, temperature, light and moisture. Every single seed of radish can grow into a seedling provided it gets an ideal environment. However, that doesn’t happen normally. The experiment examines the effect of acid, base, caffeine, and microwaves on the germination of Raphanus savitus seeds. The main purpose of the experiment was to test the negative and positive effects of different environmental factors on seed germination. The data was collected after two weeks. It ...

Introduction

Germination is the process by which a plant develops from a seed and grows in optimal conditions where temperature and water available is suitable for the transformation of a seed into a plant. The conditions are favorable when the right balance of air, moisture and temperature are reached that stimulate the seed to come out of hibernation and start sprouting a root and shoot that starts the process of germination(Bewley, J. Derek, et al). Mostly, germination is the growth of embryonic seeds. When a seed is germinating and fertilizing, it produces an embryo where an embryo is present after fertilization and this embryo gets ...

Tax Research Project 2

Introduction: In 1976, Congress amended the tax law to include Section 280A (Lawyer, 1985) in the Internal Revenue Code. Congress’ reason for the amendment was due to concerns that people were renting out their vacation homes so that they could deduct personal expenses that would not, under normal circumstances, be deductible (Lawyer, 1985). Section 280A required vacation home owners to assign expenses connected with the vacation home either to personal use or rental use. Congress apparently hoped that Section 280A would limit or control the business deductibles for expenses sustained on a vacation home during the tax year when ...

- When and where did rice emerge historically? The origin of rice has always been a debatable issue because of a multiplicity of archaeological sites that have evidence on rice planting in China, India, Thailand and parts of Africa. According to Chang (n.d.) the Chinese believe that rice originated from their country and this notion is supported by genetic studies on rice. This is backed up by the fact that China has a lot of wild rice. Rice is said to have been planted in China as early as 2700 BC. In the 1920s rice glume imprints which were dated 3200-2500 ...

Introduction

Cost price squeeze is increasing of costs when market pressures like competition make it hard to increase commodity prices in order to cover for the escalating costs. In agriculture it involves increasing costs of inputs like seeds and fertilizers and the decrease of crop prices. The farmers end up paying more than they get due to the squeeze between prices and costs. Increase of costs in upstream can be caused by energy costs fluctuation, consolidation, and inflation. When fertilizer and seed companies consolidate, there are no low cost inputs for farmers to buy. Prices on the downstream can decline ...

The use of genetically modified foods has been a controversial topic for many years. There are several potential benefits to their utilization, but some negative aspects as well. The negative aspects have been discussed earlier in this paper. There are potential human health and environmental costs to utilizing genetically modified (GM) crops. Benefits, however, may outweigh the risks. The use of genetically modified crops has provided food security, especially to developing nations. GM crops have also made food production more cost effective by reducing the amount of crop loss due to pests and weeds.

Designing a Winogradsky Column

Introduction A Winogradsky column is a micro-community designed to grow a smaller replica of a larger ecosystem. Sergi Winogradsky along with Martinus Willem Bejerink designed it when microbiology was a newly emerging science. At that time, there were few microbiological methods and most microbiologists were engaged in researching the “germ theory” of disease. Winogradsky broke away from this practice and investigated environmental by cultivating and studying microbial communities. His work furthered our understanding of microbial diversity, physiology autotrophy and environmental nutrient cycling. In particular, his efforts led to a greater understanding of sulfur and nitrogen cycling. Of particular interest in experiments that target a ...
