Can students save money by comparison shopping for textbooks at Amazon.com? To investigate this possibility, a random sample of 19 textbooks used during the Spring 2009 semester at Miami University was selected. The prices for these textbooks at both a local bookstore and through Amazon.com were recorded. The prices for the textbooks are stored in “BookPrices” data in Chapter 10_HW_Data.xls.

What assumption is necessary about the population distribution in order to perform this test?
