Each of 51 golfers hit three golf balls of brand X and three golf balls of brand
Question:
Each of 51 golfers hit three golf balls of brand X and three golf balls of brand Y in a random order. Let Xi and Yi equal the averages of the distances traveled by the brand X and brand Y golf balls hit by the ith golfer, i = 1, 2, . . . , 51. Let Wi = Xi − Yi, i = 1, 2, . . . , 51. Test H0 : μW = 0 against H1 : μW > 0, where μW is the mean of the differences. If ¯w = 2.07 and s2W = 84.63, would H0 be accepted or rejected at an α = 0.05 significance level? What is the p-value of this test?
