Introduction

Statistics is a branch of mathematics, aimed at collecting and analyzing data via different methods such as analysis of variance, kurtosis, skewness or regression analysis. Nowadays, statistics helps processing data with a help of creating various charts that in turn help visualizing complex data sets. There are two major types of statistics, descriptive statistics and inferential statistics. Descriptive and inferential statistics require proper hypothesis formation and thus proper selection of the statistical tests that in turn have to be analyzed and interpreted successfully.

Descriptive Statistics

Descriptive statistics implies application of various coefficients that simplify process of data processing and aggregation (Trochim, ...

Report on the relationship between assets and sales

Executive summary A company’s investment in foreign assets has a bearing on the amount of foreign sales it makes. The regression analysis indicates a positive association between the ratio of foreign sales to total sales and the ratio of foreign assets to total assets. This implies that transnational companies should invest more in foreign assets to improve their foreign sales. They should also consider other factors affecting foreign sales such as international marketing strategies including advertising expenditure, among others. Investment in foreign assets is not the only contributor to foreign sales as indicated by the model’s coefficient ...

The Solow Model

For long, the concept of economic change has been interesting economists. The reasons why some of the countries are poor while others are rich or even the understanding of why some nations grow faster than others has constantly disturbed the understanding of most economists. The theory of economic growth has been put upfront in explaining the growth indices of different nations. In its place, the theory of economic growth aims at explaining whether poor countries can grow faster than their rich counterparts, catch up with them and close their income gaps, that is converge. Elaborated by Trevor Swan and ...

If a fuel mixture can be represented by the general formula CxH2x, prove that the stoichiometric gravimetric air/fuel ratio is 14.8:1.

The combustion reaction for a given fuel mixture will look as follows:

CxH2x + 1.5x(O2 + 3.76N2) → xCO2 + xH2O + 1.5x*3.76N2 The molar ratio is 1.5x:1, to find the gravimetric ratio, the masses of the air and fuel should be found. This can be done by multiplying molar ratio with molar weights of the fuel and air. m(fuel) = 12*x + 2x*1 = 14x m(air) = 1.5x(16*2 + 3.76*14*2) = 1.5x*137.28 = 205.92x The gravimetric stoichiometric air/fuel ratio then is 205.92x:14x = 14.71:1 The dry exhaust gas analysis from an ...

<Insert Name> <Insert Submission Date> <Insert Chairperson Name>

Introduction

The goal of therapies addressing weight loss is to decrease the risks for chronic diseases such as diabetes and hypertension, but also to ultimately increase positive feelings of well-being from physical improvements. Significant weight loss is accompanied by both positive and negative emotions and if the decrease in body mass is accompanying by negative feelings, maintenance is difficult. Therefore, psychological aspects to weight loss programs are an important consideration when determining the success of the therapy. Previous research concerning the psychological aspects of significant weight loss has made ...

Abstract

Can female participation in the labor force contribute to economic growth? Is there a causal relationship between female participation in the labor force and economic growth? This paper addresses these questions using the vector error correction model. For this study, an annual time series data for the period 1970 to 2012 for the United States has been used. The results show that there exists a co-integration between female participation and GDP per capita, which is a proxy measure for economic development. The result does not support a two-way causality between the variables. However, a causality running from GDP per ...

The Guilford-Zimmerman Temperament Survey (GZTS) was developed in 1948 by J. P. Guilford and W. S. Zimmerman for measuring normal personality development and temperament. The reason for developing personality trait measuring instruments in the field of psychology was the simplification of tests used to measure personality traits. Early tests usually focused on theories relevant to particular traits, which resulted in the creation of several hundred different tests, each measuring only one trait (McCrae & Costa Jr., 2012). Though many tests had good psychometric properties, there was no unified personality test, so the administration and interpretation of different test was disorganized ...

Abstract

The fugacity is a term that has Latin origins, referring to pace and speed. Early work somewhere in the 20th century, on fugacity, demonstrated that chemical equilibrium is established by the free energies of reacting material. Since then, various approaches and concepts on fugacity have been provided. The gas fugacity of noble gasses has been studied, and models have been proposed for calculating the solubility of noble gasses. The development of various models has considered pressure effects, differential equilibrium between components and temperature changes. The paper discusses the evolution of various multimedia fugacity models and the fugacity of pure ...

Simplex method is an algorithm for solving linear programming optimization problem by sorting the vertices of a convex polyhedron in a multidimensional space. Linear programming problem is that it is necessary to maximize or minimize a linear functional on a multidimensional space for a given linear constraints.

The sequence of calculations simplex method can be divided into two main phases:

- finding the original vertices of the set of feasible solutions, - gradual transition from one vertex to another, leading to the optimization of the objective function. Thus in some cases, the initial solution is obviously its definition or does not require complex calculations, for example, when all the constraints are represented by inequalities of ...

Abstract

Like many other countries in the Middle East, Saudi Arabia has the access to the crucial natural resource – oil. Unlike some of its neighbors, it has been succeeding in making most of it – the country is not drawn into political troubles (Jones, N/A) and is relatively rich. Despite international criticism related to violation of human rights (the country is one of the world leaders in terms of enforcement of capital punishment), generally, Saudi Arabia is doing relatively well in both economic and political terms. The purpose of this paper is to provide a regression model that estimates how much of ...

The fundamental theorem of algebra (FToA) is states that each non-constant single-variable polynomial with complex coefficients has at least one complex root. In fact, there are many equivalent formulations, such as this: every real polynomial can be represented as a product of real linear and real quadratic factors. Early studies equations by al-Khwarizmi (from 800) are devoted only to positive real roots and have no relation to the FToA. Cardano was the first to realize that it is possible to work with the values ​​more general than real numbers (Geuvers, Wiedijk & Zwanenburg, 2002). This discovery was made in the ...

Abstract

This paper presents the findings of three regression analysis performed on American InterContinental University’s survey data. They include regression analysis for intrinsic satisfaction versus benefits, extrinsic satisfaction versus benefits and overall satisfaction versus benefits. The coefficient of determination for each analysis was found to be 0.0042629, 0.000018508, and 0.0025798 respectively. In each case the coefficient of correlation was found to be less than 0.1.
