17. Starting Salaries, again College graduates with STEM majors have starting salaries that appear to be much better than those in non-STEM majors.14 Starting salaries for 50 randomly selected graduates in electrical engineering and 50 randomly selected graduates in computer science were compiled with the information that follows.

a. What is the point estimate of the mean difference between starting salaries for electrical engineers and computer scientists?

b. Find a 95% lower confidence bound for the mean difference between starting salaries for electrical engineers and computer scientists. Does it appear that electrical engineers have a higher starting salary than computer scientists?
