Question:

A sporting goods manufacturing company wanted to compare the distance traveled by golf balls produced using each of four different designs. Ten balls of each design were manufactured and brought to the local golf course for the club professional to test. The order in which the balls were hit with the same club from the first tee was randomized so that the pro did not know which type of ball was being hit. All 40 balls were hit in a short period of time, during which the environmental conditions were essentially the same. The results (distance traveled in yards) for the four designs are stored in Golfball:
a. At the 0.05 level of significance, is there evidence of a difference in the median distances traveled by the golf balls with different designs?
b. Compare the results of (a) with those of Problem 11.14 (a) on page 429.
