Given the following null and alternative hypotheses, complete parts a and b. H,: 62 =100 0 Hp: 02 #100 a. Testwhen n=26, s=9, and a=0.10. Be certain to state the decision rule. State the decision rule. Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice. (Round to four decimal places as needed.) If the test statistic, x2 > x(2).05 = 37.6525', reject Hy, or if the test statistic, x2 < Xg.gs = 14.61 14', reject Hy. If the test statistic, x > xfi =, rejectH,. If the test statistic, x2 < x? —a = s rejectH,. Find the test statistic, X2- x2 = 20.25 (Type an integer or a decimal.) Choose the correct conclusion below. Reject Hy. There is insufficient evidence that o2 #100. Do not reject H,. There is sufficient evidence that 6% # 100, - Reject Hy. There is sufficient evidence that o2 # 100. ¥ U Do not reject Ho- There is insufficient evidence that 62 # 100. b. Test when n=23, s=5, and aa=0.05. Be certain to state the decision rule. State the decision rule. Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice. (Round to four decimal places as needed.) If the test statistic, x2 > xi =, rejectH,. _ 2 _ . If the test statistic, x2 <X1-o= rejectH. Y If the test statistic, x2 > xfi /o = 36.7807 , reject Hy or if the test statistic, x2 < xf —a/2 = 10.9823, reject Hy. Find the test statistic, x2 xz = 5.5 (Type an integer or a decimal.) Choose the correct conclusion below. Do not reject Hy. There is insufficient evidence that o2 #100. Reject H,. There is insufficient evidence that 62 # 100. - Do not reject Hy. There is sufficient evidence that o2 #100. ¥'D. Reject Hy. There is sufficient evidence that 62 # 100.
