Question

Farther is better in golf, being able to drive the ball farther is likely to lead to better (lower) scores. Using data from the Ladies Professional Golf Association (LPGA) in a recent year, a linear model was used to predict y = scoring average from x = average driving distance (in yards).62 Here is the residual plot for that model. Use it to determine whether the regression model is appropriate.

Answer 1

The regression model is appropriate because the residual plot follows a random pattern. The data are evenly scattered about the x-axis.
