Use technology to help you 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> 1170; x = 0.08; a=207.79. Sample statistics: x= 1198.51, n = 250 Identify the null and alternative hypotheses. Choose the correct answer below. OA. Ho: H21170 H₂H<1170 OB. Ho: s1198.51 H₂: > 1198.51 OC. Ho: 21198.51 H: 1198.51 OE. Ho: > 1198.51 Ha: HS1198.51 Calculate the standardized test statistic. The standardized test statistic is (Round to two decimal places as needed.) Determine the P-value. P= (Round to three decimal places as needed.) Determine the outcome and conclusion of the test. Ho. At the 8% significance level, there OD. Ho: > 1170 Haus 1170 OF. Ho: HS1170 H₂H1170 enough evidence to the claim.
