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: H 2 8200; a = 0.10 Sample statistics: x = 8000, s = 480, n = 25 . . . What are the null and alternative hypotheses? O A. Ho: H = 8200 O B. Ho: HIS 8200 Ha: H # 8200 Ha: H > 8200 O C. Ho: H 2 8200 O D. Ho: H # 8200 Ha: H
