Use 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: μ2 7800; α-0.01 Sample statistics: x = 7600, s = 420, n= 24 What are the null and alternative hypotheses? O A. Ho: µ#7800 Hai H = 7800 O B. Ho: µs7800 Hi u> 7800 O D. H: µ = 7800 O C. Ho: H2 7800 H3: u<7800 H: u#7800 What 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? P= (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. At the 1% level of significance, there is not enough evidence to reject the claim. O B. Fail to reject Ho. At the 1% level of significance, there is enough evidence to reject the claim. C. Reject Ho. At the 1% level of significance, there is enough evidence to reject the claim. D. Reject Ho. At the 1% level of significance, there is not enough evidence to reject the claim. O O
