Use a ttest to test the claim about the population mean u at the given level of significance 0: using the given sample statistics. Assume the population is normally distributed. Claim: u at 26; o: = 0.05 Sample statistics: )2: 24.3, s = 4.8, n =13 (:i What are the null and alternative hypotheses? Choose the correct answer below. 5:} A. H0: u226 {:2} B. H0: u 526 Ha:u26 i") C. H0: u: 26 {I} D. H0: u #26 Ha.p26 Haill=26 What is the value of the standardized test statistic? The standardized test statistic is D. (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. O A. Fail to 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. O C. Reject Ho. There is not enough evidence to support the claim. O D.
