10.) Two samples are randomly selected and come from normal populations. The sample statistics are: x, = 1080, s1 = 83, m = 20, x, = 950, $2 = 205, and n2 = 17. Assume that 01 # 02. Use a = 0.05 (a) Test the claim that uj > ur (18 pts) The claim: The opposite or complement: Ho: HI: a = Is the test left-tailed, right-tailed, or two-tailed? Is the required distribution a z, t, or a y' distribution? (Circle) The critical value(s) for this test: The calculator hypothesis command used: The test statistic = The P-value = The test statistic: does fall / does not fall in the critical rejection region therefore reject / fail to reject the null hypothesis Ho. The P-value = is / is not S a = therefore reject / fail to reject the null hypothesis Ho. There is insufficient / sufficient evidence to support the claim. (b) Find a 95 % confidence interval estimate about the difference between the population means. (5 pts)
