Statistics

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.
