Use technology and a t-test to test the claim about the population mean µ at the given level of significance a using the given sample statistics. Assume the population is normally distributed.Claim: μ> 70; x = 0.05 Sample statistics: x = 73.1, s = 2.9, n = 29What are the null and alternative hypotheses? Choose the correct answer below.O A. Ho: μ#70HA: μ = 70OC. Ho: μ≤ 70HA: μ> 70What is the value of the standardized test statistic?The standardized test statistic is (Round to two decimal places as needed.)What is the P-value of the test statistic?P-value = (Round to three decimal places as needed.)Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below.O A. Fail to reject Ho. There is not enough evidence to support the claim.B. Fail to reject Ho. There is enough evidence to support the claim.O C. Reject Ho.
