- What are the two types of statistics? (5pts.)

The two types of statistics are descriptive and inferential. In descriptive statistics, the data of a population is summarized graphically or numerically through derivation of statistics related to central tendency and dispersion around the same. The shape and nature of distribution is also used in descriptive statistics.
In inferential statistics, the parameters of a population are inferred according to sample statistics. This involves the estimation of statistics of a group allowing for approximation of information data relating to the entire population. In this type of statistics, modeling are used to generate mathematical ...

Financial Model is usually known as a mathematical model represents the asset class of a financial based asset or a portfolio of a business or an individual . The essence of financial modeling is increasing day by day in number of countries ...

In statistics, distribution of a data population pertains to how data is spread out within the given population and how these are arranged. There are several statistical measures that used in describing how specific data are spread out within a given population. One is by using the ranger which measures the ranged of values within a population, the deviation, which is the difference each value in the population from the mean among others. The statistic or measure of dispersion that looks into the looseness or tightness of data is the standard deviation. It measures how often a data deviates from the norm of ...

The scatter plot against the expenditure per customers and the square root of races fits the best linear regression graph than the number of races. In statistics the slope of square roots makes the best fit ...

Measurement in this case refers to use and application of rules for assigning numbers to different objects. Different measurement scales are applied for different classes of objects. For instance, measuring a height of a sample population may be done in inches, whereas the weight of the sample population may be done in kilograms. The scale measurement constitutes three important properties. According to Kaplan and Saccuzzo (27), these are magnitude, absolute zero, and equal intervals. Magnitude refers to the ability to represent more, less or equal attributes of a given entity or object. This is clearly shown in a scale of weight where one ...

1. Role a sample plays in making statistical inferences about the population

The sample plays an essential role in the process of making statistical inferences about the population. Ordinarily, the entire population is usually too large to be fully studied. The limitations that limit study of an entire population include costs, time and convenience in the application of the study modes. A sample from the entire population is selected. It is assumed that the sample would be representative of the entire population and contains minimum bias towards any aspect of the population. The sample, therefore, forms the basis on which the population characteristics are inferred. The researchers assume that the characteristics ...

“Growth” and “development” are not the same. Growth means specific observable physical changes taking place in a child throughout most of his life due to increase in both the quantity and size of the existing body cells. These include increase in height, weight, head circumference, body shape, and shoe size as well as the length of the arms & legs. Development, on the other hand, is progressively evolutionary process of advancement from simplicity to complexity, along a defined path, marked by increased intelligence, knowledge, behavior and skill-sets. The growth and development cycle gauges the actual developmental progress using two ...

1. Describe the role probability information plays in the decision-making process.

Decision making involves selecting best alternative based on personal values and preferences. Therefore, a decision can only be made from some possible alternatives provided. The decision arrived is taken to be rational if it was the one which had the highest probability of success and it serves the decision makers life goals, desires, values and lifestyle. Likewise, in business organization the managers strive to make decisions which can propel an organization towards achieving its goals. They always consider the probability of an event occurring or even not occurring, and then they settle on one of the possible alternatives (McClave, Benson, ...

With anxiety disorders, people often feel stressed out or panicked, as they cannot stop worrying about aspects of their life or work to the point where it is debilitating. They often compulsively perform actions in order to stave off the anxiety, and they also do not understand how to completely relax. They are constantly at a heightened state of awareness, and their ability to deal with stress is at an all time low. They simply cannot maintain any sense of calm.
Treatments for this include cognitive behavioral therapy and medications; these can allow the patient to understand the causes ...

Question 1

Residual income (RI) is calculated as the difference between the operating income and the minimum return on the assets. RI = Accounting income – (min rate of return (%) × average operating assets). If RI > 0, then the company is earning more than the hurdle rate (minimum rate of return), thus the proposed project is desirable. Value Added (EVA) is a special case of RI, calculated as the difference between net income (operating income after tax) and the cost of capital per annum. Therefore, unlike RI, EVA calculates the actual cost of capital, instead of the minimum rate of return and considers after-tax ...

1. a) Below is the decision tree that I have used to recommend the unit price to quote the customer based on greatest benefit to Capstick Limited.

From the decision tree, it is clear that the unit price that would accrue maximum benefit to the company is that of selling the units at £17, through sub-contracting.
b) Objective comparison of the in-house manufacture and sub-contracted routes shows that the sub-contracted route is more beneficial to the company since the production cost is lower by £0.5 per unit. The main disadvantage, however, is that this sub-contracted route rigidly fixes the units ...

Introduction

Consumer dissatisfaction normally leads to sales decline and switching of customers loyalty to another brand of product. Inability in meeting consumer expectation due to reduction in quality or quantity leads to dissatisfaction. According to , consumers use the height of the container in making volume judgment.

Question 1

In business terms, risk can be explained as the inability to make correct anticipations or predictions about the incomes a business expects to realize in the future. A business faces risk due to the fact that it cannot accurately predict whether it will earn enough money to sustain its existence in future periods. Diversification, on the other hand, refers to the process of making several different investments that are not related so as to reduce the level of risk an investor faces.

Businesses may measure the amount of risk they face by analyzing the level of standard deviation they record ...
