Question

In a wage discrimination case involving male and female employees, independent samples of male and female employees with 5 or more years of experience in the same position provided the following salary data (in thousands):

FEMALE: 28, 25, 26, 27, 27, 26, 28, 24, 25, 29, 29, 29

MALE: 26, 23, 25, 23, 27, 24, 29, 27, 23, 26, 26, 24

A. Using the partial Excel output provided below, construct a 95% confidence interval estimate of the mean difference in salaries for male and female employees. Be certain that your interval estimate is in the correct final format, as discussed in class. Interpret the practical meaning of this interval estimate, in plain English.

B. Using the partial Excel output provided below, and a significance level of α = .05, do the sample data suggest that there is a significant difference between the average salaries of male and female employees? Do a complete and appropriate hypothesis test using the critical value approach and the 5-step procedure discussed in class.

C. Using only the appropriate statistical table in your textbook, what is the most accurate statement you can make about the p-value of the hypothesis test you conducted in part B?
