Calculate the pair-wise correlation coefficients between Exports and each of the other variables. Test the statistical significance of each correlation coefficient.

The relationship between firm exports, size, productivity and skill/capital intensity (Excel)

Maximum project length: 3,000 words

The relationship between firm exports, size, productivity and skill/capital intensity

Firm-level exports are potentially affected by a number of factors including the size of a firm, its productivity as well as the skill and capital intensity of its production technology.

The objective of this project is to establish whether size, productivity, skill intensity and capital intensity are determinants of firm exports in a cross-section of firms.

The data below contains information, covering a sample of 60 firms, on firm exports (Exports), a commonly used measure of firm size and in particular the number of employees of the firm (Empl), a measure of the productivity of the firm (Prod), as well as a measure of the skill intensity (Skill) and capital intensity (Capit) of the firm. Exports are measured in million pounds while productivity is measured as the ratio of the value of sales to the value of inputs used. Skill intensity is measured as the average number of years of schooling of the employees while capital intensity is measured as the ratio between the capital stock of a firm in million pounds and the number of employees.

Describe the data, using summary statistics and graphs, as appropriate.

Calculate the pair-wise correlation coefficients between Exports and each of the other variables. Test the statistical significance of each correlation coefficient.

Consider the two variables Skill and Capit. Compute the pairwise correlation of the two variables and test the significance of the correlation coefficient.

Consider again the two variables Skill and Capit and test the null hypothesis that the two variables have equal variance.

Write an implicit but exact formula for λn in terms of the point x = 12 and the function f (x, λ) = λx(1 −x).

Statistic Problems

Numerics of superstable cycles

Let λn denote the value of λ at which the logistic map, f (x, λ) = λx(1 −x) has a superstable cycle of period 2n.

Write an implicit but exact formula for λn in terms of the point x = 12 and the function f (x, λ) = λx(1 −x). (You will find lots of inspiration in the lecture notes, if not this very equation).

Using a computer and the result of part (a), find λ2, λ3, …, λ7 to three significant digits. Hint: formulate the problem as one where you have to find the zero of a function. Alternatively, you could make pictures, zoom in, and find those zeros by hand.

Evaluate (λ3 −λ2)/(λ4 −λ3). This will approximate the other universal constant of the period-doubling route to chaos. The problem is that success of this assignment depends a little on success of the previous one. If necessary, you could revert to (λ2 −λ1)/(λ3 −λ2). Be practical, this you would typically face in an experiment.

NORC uses data sampling techniques with the GSS to strive to obtain a representative sample of US adults. In your early analyses of your project data, what did you learn about each individual variable? Did the numbers surprise you? Why or why not? Based on your crosstabs and measures of association, does it look like your variables have a relationship?

Test Bias

Locate an example of test bias (any type of test) from the trade literature or the popular press (e.g., online newspaper or magazine).

Describe the main points in the example,followed by your own opinion about this issue.

Be sure to include a discussion of what can be done to minimize test bias in this specific situation. Include a copy of the article at the end of your paper.

Hypothesis

This is for a College STATISTICS Class.

Area of study is (Health Information Management)

Research Hypothesis (Relative Measures of Disease Frequency)

Create a research hypothesis in your area of study (Health Information Management) that would be answered using either a z- or a t- test. Include the following:

Introduction: Brief description of the study including the purpose and importance of the research question being asked.

What is the null hypothesis?What is the research hypothesis?

Participants/Sampling Method: Describe your sampling method. What is your sample size? Who is your population of interest? How representative is the sample of the population under study?

Data Analysis: Describe the statistical analysis. What is your variable? What is its level of measurement? What is your alpha level?

Results & Discussion: Did you reject the null hypothesis? What information did you use to lead you to your conclusion? Was your p value greater than or less than your alpha?
