a. Develop a 95% confidence interval estimate of the difference between the starting salaries for the two majors.
b. Using α\alpha = .10, test to determine if the average starting salary for an MIS graduate is $4,000 more than the starting salary for a finance graduate. Use both the critical value and p-value approaches to hypothesis testing. (Hint: the null hypothesis is H0: μ\mu 1 - μ\mu 2 = $4,000, where μ\mu 1 is the average starting salary of MIS graduates.)
