Use technology and a t-test to test the claim about the population mean u at the given level of significance a using the given sample statistics. Assume the population is normally distributed. Claim: u> 75; a 0.01 Sample statistics: x= 78.1, s=3.3, n=23 What are the null and altemative hypotheses? Choose the correct answer below. B. Ho: HS75 O A. Ho: H= 75 Ha H#75 Ha: u> 75 O D. H,: µ#75 OC. Ho: u2 75 Ha: H= 75 Ha: H<75 What is the value of the standardized test statistic? The standardized test statistic is 4.51. (Round to two decimal places as needed.) What is the P-value of the test statistic? P-value = 0.000 (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. Reject Ho. There is not enough evidence to support the claim. O B. Fail to reject Ho. There is enough evidence to support the claim. OC. Fail to reject Ho. There is not enough evidence to support the claim. O D. Reject Ho. There is enough evidence to support the claim.

Use technology and a t-test to test the claim about the population mean u at the given level of significance a using the given sample statistics. Assume the population is normally distributed. Claim: u> 75; a=0.01 Sample statistics: x= 78.1, s= 3.3, n=23 What are the null and altemative hypotheses? Choose the correct answer below. B. Ho: HS75 O A. Ho: u= 75 Ha: u> 75 O D. Ho: H#75 OC. Ho: µ2 75 Ha: u<75 Ha u= 75 What is the value of the standardized test statistic? The standardized test statistic is 4.51. (Round to two decimal places as needed.) What is the P-value of the test statistic? P-value = 0.000 (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. Reject Ho. There is not enough evidence to support the claim. O B. Fail to reject Hp. There is enough evidence to support the claim. OC. Fail to reject Ho. There is not enough evidence to support the claim. O D. Reject Ho- There is enough evidence to support the claim.
