As a group, students majoring in engineering disciplines have the highest salary expectations, followed by those studying the computer science fields, according to the results of a study. To compare the starting salaries of college graduates majoring in electrical engineering and computer science, random samples of 60 recent college graduates in each major were selected and the following information obtained. Major Mean ($) SD Electrical Engineering 62,232 12,900 Computer science 57,965 13,930 (a) Find a point estimate for the difference in the average starting salaries (in dollars) of college students majoring in electrical engineering and computer science. (Use electrical engineering - computer science.) $ 4,267 What is the 95% margin of error (in dollars) for your estimate? (Round your answer to two decimal places.) $ 1.96 (b) Based upon the results in part (a), do you think that there is a significant difference in the average starting salaries for electrical engineers and computer scientists? Explain. Since the margin of error of the estimate of the difference µ, - µ, allows both positive and negative v engineering majors cannot be said to be different from v estimates, the mean expected salary for electrical the mean for computer science majors.
