Test the claim about the population mean, u, at the given level of significance using the given sample statistics. Claim: u =40; a = 0.05; o = 3.45. Sample statistics: x = 39.3, n =56 Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho: 1=40 O B. Ho: p # 40 Ha: H 40 O D. Ho: H = 40 Ha: H = 40 Ha : 1 # 40 O E. Ho: p 40 Calculate the standardized test statistic. The standardized test statistic is (Round to two decimal places as needed.)Determine the critical value(s). Select the correct choice below and fill in the answer box to complete your choice. (Round to two decimal places as needed.) O A. The critical value is O B. The critical values are + Determine the outcome and conclusion of the test. Choose the correct answer below. O A. Fail to reject Ho. At the 5% significance level, there is not enough evidence to reject the claim. O B. Reject Ho. At the 5% significance level, there is enough evidence to support the claim. O C. Reject Ho. At the 5% significance level, there is enough evidence to reject the claim. O D. Fail to reject Ho. At the 5% significance level, there is not enough evidence to support the claim
