A golf ball maker is interested in analyzing the relationship between the club head speed that a male player achieves when he uses a driver and the distance the ball travels. The sample data are listed here.

Club Speed (mph) ....................... Distance (yards)
95 .................................................................. 233
97 .................................................................. 246
91 .................................................................. 202
103 ................................................................ 240
118 ................................................................ 289
88 .................................................................. 196
93 .................................................................. 227
97 .................................................................. 217
101 ................................................................ 245
104 ................................................................ 256
95 .................................................................. 218

a. Develop a regression model using club speed as the independent variable and driving distance as the dependent variable. What percentage of the variation in the driving distance is explained by the club head speed?
b. Test using an alpha = 0.05 level to determine if the regression slope coefficient is statistically significant.
c. Use the regression model to describe the relationship between club speed and driving distance.
