# Question: In exercise 9 data contained in the file named PGA

In exercise 9, data contained in the file named PGA Driving Dist (PGA Tour website, November 1, 2012) were used to develop an estimated regression equation to predict the average number of yards per drive (y) given the ball speed (x1) and the launch angle (x2). The estimated regression equation was y = 81.6 + 1.09x1 + 1.65x2.

a. Does the estimated regression equation provide a good fit to the data? Explain.

b. In part (b) of exercise 9, an estimated regression equation was developed using only ball speed to predict the average number of yards per drive. The estimated regression equation was y = 117 + 0.988x1. Compare the fit obtained using just ball speed to the fit obtained using ball speed and the launch angle.
