Test the claim about the population mean, μ, at the given level of significance using the given sample statistics. Claim: -40; a=0.09; 3.18. Sample statistics: x= 38.9, n=63 Identify the null and altemative hypotheses. Choose the correct answer below OA. H₂40 H₂:40 OC. ₂40 H₂<40 OE H40 H₂H40 Calculate the standardized test statistic The standardized test statistic in CLIED B. H₂:40 H₂ #40 OD. H:40 H₂:40 OF H40 H₂:40
(Mount (wo decimal praces) OA. The critical value is OB. The critical values are t Determine the outcome and conclusion of the test. Choose the correct answer below. OA Reject Ho. At the 9% significance level, there is enough evidence to support the claim B. Fail to reject Ho. At the 9% significance level, there is not enough evidence to reject the claim, OC. Fail to reject Ho. At the 9% significance level, there is not enough evidence to support the claim. OD. Reject Ho. At the 9% significance level, there is enough evidence to reject the claim.
