document. Be sure to show all of your work and clearly label all calculations. All
statistical calculations will use the Included in the Week Two tab of theEmployee Salary
Data Set are 2 one-sample t-tests comparing male and female average salaries to the
overall sample mean. 1. Below are 2 one-sample t-test comparing male and female
average salaries to the overall sample mean. Based on our sample, how do you interpret
the results and what do these results suggest about the population means for male and
female salaries? 2. Based on our sample data set, perform a 2-sample t-test to see if the
population male and female average salaries could be equal to each other. (Since we have
not yet covered testing for variance equality, assume the data sets have statistically equal
variances.) 3. Based on our sample data set, can the male and female compas in the
population be equal to each other? (Another 2-sample t-test.) 4. Since performance is
often a factor in pay levels, is the average Performance Rating the same for both genders?
5. If the salary and compa mean tests in questions 2 and 3 provide different results about
male and female salary equality, which would be more appropriate to use in answering
the question about salary equity? Why? What are your conclusions about equal pay at this
point??
