The number of passes completed and the total number of passing yards for Tom Brady, quarterback for the New England Patriots, were recorded for the 16 regular games in the 2006 football season. Week 6 was a bye and no data was reported.

a. What is the least-squares line relating the total passing yards to the number of pass completions for Tom Brady?

b. What proportion of the total variation is explained by the regression of total passing yards (y) on the number of pass completions (x)?

c. If they are available, examine the diagnostic plots to check the validity of the regression assumptions.
