A curious college student is interested in how the number of pages in a book affects the price of the book. His conjecture is that as the number of pages goes up, so does the price of the book.

To test his conjecture, you will perform a simple linear regression in StatCrunch on the variables Pages (the number of pages in the book) and Amazon (the price of the book at Amazon). Click this link to get to the data set in StatCrunch.
