# Question

The Insurance Institute for Highway Safety has listed the following ratings based on collision and comprehensive claims for 12 makes of midsize fourdoor cars from the 2005–2007 model years. Higher numbers reflect higher claims in the collision and comprehensive categories of coverage.

a. Determine the least-squares regression line for predicting the rate of collision claims based on comprehensive claim rating.

b. Calculate and interpret the values of r and r2.

c. If a new model were to have a comprehensive claim rating of 90, what would be the predicted rating for collision claims?
