O H;: (u, - 4,) = 0 versus H.: (4, - H,) > 0 O Ho: (H, - H2) = 0 versus H: (u, - u2) < 0 O H,: (4, - 42) = 0 versus H: (u, - 42) # 0 O H: (H, - H2) < 0 versus H.: (4, - H2) > 0 O Ho: (u, - u2) # 0 versus H: (u, - 42) = 0 Calculate the pooled estimate of o?, the associated degrees of freedom, and the observed value of the t statistic. (Round s? and your t statistic to three decimal places. s2 = df = t = What is the rejection region using a = 0.05? (If the test is one-tailed, enter NONE for the unused region. Round your answers to three decimal places.) t>
