The ratings below are based on collision claim experience and theft frequency for 12 makes of small, two-door cars. Higher numbers reflect higher claims and more frequent thefts, respectively.

a. Determine the least-squares regression line for predicting the rate of collision claims on the basis of theft frequency rating.

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

c. If a new model were to have a theft rating of 110, what would be the predicted rating for collision claims?
