Question:

As a group, students majoring in the engineering disciplines have the highest salary expectations, followed by those studying the computer science fields, according to results of NACE's 2010 Student Survey. To compare the starting salaries of college graduates majoring in engineering and computer science (see Exercise 8.49), random samples of 50 recent college graduates in each major were selected and the following information obtained.

a. Do the data provide sufficient evidence to indicate a difference in average starting salaries for college graduates who majored in engineering and computer science? Test using Î± = .05.
b. Compare your conclusions in part a with the results of part b in Exercise 8.49. Are they the same? Explain.
