A random sample of 40 PGA golfers was taken. The dataset is in the file PGAdriver.xls. A
researcher is trying to predict (driving) accuracy using (driving) distance.
1. Plot Accuracy vs. Distance and describe.
2. Find least squares regression line and interpret slope in the words of the problem.
3. Find the coefficient of determination (R?) and interpret.
4. Find the correlation coefficient (R) and interpret.
5. Find and interpret a 95% Confidence Interval for the true slope.
6. Find the predicted values for Perry, Stadler and Trahan.
7. Find the residuals values for Perry, Stadler and Trahan
8. Graph the standardized residuals vs. predicted values (x-axis). Describe and comment.
9. Graph the predicted values vs. the actual accuracy values (x-axis). Describe and
comment.
10. Make a normal probability plot of the standardized residuals. Describe and comment.
