Apperson and Fitz is a chain of clothing stores that caters to high school and college students. It publishes a quarterly catalogue and operates a Web site that features provoca- tively attired males and females. The Web site is very expensive to maintain, and company executives are not sure if the number of hits at the site relate to sales; that is, people may be looking at the site for the pictures rather than as potential customers. The Web master has accumu-
lated the following data for hits per month and orders placed at the Web site for the past 20 months. Develop a linear regression model for these data and indi- cate if there appears to be a strong relationship between Web site hits and orders. What would be the forecast for orders with 60,000 hits per month?
