Hypotheses for a statistical test are given, followed by several possible confidence intervals for different samples. In each case, use the confidence interval to state a conclusion of the test for that sample and give the significance level used. In addition, in each case for which the results are significant, state which group (1 or 2) has the larger mean. Hypotheses: Ho : MI = #2 VS Ha : M # 12 (a) 95 % confidence interval for 1 - /2: 0.16 to 0.41 Conclusion: Ho Significance level: Group with the larger mean: (b) 99 % confidence interval for , - M2: -2.7 to 5.3 Conclusion: Ho Significance level: Group with the larger mean: (c) 90 % confidence interval for , - /2: -10.8 to-3.0 Conclusion: Ho Significance level: Group with the larger mean
