Asked by Julie Ann

You are working as an assistant to the dean of institutional research at your university. She wants to survey members of the alumni association who obtained their baccalaureate degrees 5 years ago to learn what their starting salaries were in their first full-time job after receiving their degrees. A sample of 100 alumni is to be randomly selected from the list of 2,500 graduates in that class. If her goal is to construct a 95% confidence interval estimate for the population mean starting salary, why is it unlikely that you will be able to use Equations (8.1) on page 255 for this purpose? Explain.
