A sporting goods manufacturing company wanted to compare the distance traveled by golf balls produced using four different designs.
A sporting goods manufacturing company wanted to compare the distance traveled by golf balls produced using four different designs. Ten balls were manufactured with each design and were 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. The results (distance traveled in yards) for the four designs are provided in the accompanying table.
