Question

$**Question I.** Each of 51 golfers hit three golf balls of brand X and three golf balls of brand Y in a random order. Let $X_i$ and $Y_i$ equal the averages of the distances traveled by the brand X and brand Y golf balls hit by the i-th golfer, $i = 1, 2, \ldots, 51$. Let $W_i = X_i - Y_i$, $i = 1, 2, \ldots, 51$. Test $H_0: \mu_w = 0$ against $H_1: \mu_w > 0$, where $\mu_w$ is the mean of the differences. Let $\bar{w} = 2.07$ and $s^2_w = 84.63$ be the observed sample mean and sample standard deviation of $W_i$'s. Would $H_0$ be accepted or rejected at an $\alpha = 0.05$ significance level? What is the P-value of this test?$
