13. There are two schools of thought in teaching bowl-ing. Some say you should look at the "pocket" (the space between the first and third pins) as you release the ball, whereas others say you should look at a "spot," a point on the lane about 10 feet in front of the foul line. A bowling instructor decides to test these ideas with his new class of 24 students. He randomly assigns them to one of two groups. He teaches one group (the "pocket" group) to look at the pocket and the other (the "spot") group to look at the spot. At the end of the eight-week series of lessons, he has the members of each group bowl one game and records their scores. Is one method better than the other? Use the 5 steps of hypothesis testing. Pocket group score summary: n1 = 12, X1 = 127.2, s1 = 14.6 Spot group score summay: n2 = 12, X2 = 134.4, s2 = 11.8
