Suppose Golf Magazine would like to do an article comparing the driving distances of various golf balls. Eight golfers were asked to hit Top Flite, Pinnacle, and Titleist golf balls with their drivers. The distance for each shot was measured in yards and is as follows. The file golf balls. xlsx also contains these data.

a. Using α = 0.05, does there appear to be a difference in the driving yardage of the balls?

b. Was blocking effective? Why or why not?

c. If warranted, determine which pairs of balls were different using α = 0.05.

d. Verify your results with Excel.
