How is the number of pages in a textbook related to the price of the textbook? To find out, two Cal Poly freshmen (2006) randomly selected 30 textbooks at the campus bookstore and recorded the price ($) and number of pages for each book. Here's output from analyzing the data collected in the Corr/Regression applet. Assume, for now, that the normal approximation-based method is valid, and thus, the p-value from the Regression Table below is valid.
-We can conclude that the price of a textbook will increase if we add more pages.
