Use a t-test to test the claim about the population mean at the given level of significance a using the given sample statistics. Assume the population is normally distributed Claim: 2 8300; « +0.10 Sample statistics: x=8100, s = 450, n=20 What are the null and alternative hypotheses? O A. Ho: 58300 H:>8300 O C. Ha: H = 8300 Hu*8300 OB. Ho: = 8300 H: *8300 OD. Ho: 28300 H: < 8300 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? (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. PE A. Reject Ho. At the 10% level of significance, there is enough evidence to reject the claim B. Fail to reject Ho At the 10% level of significance, there is not enough evidence to reject the claim. C. Fail to reject Ho At the 10% level of significance, there is enough evidence to reject the claim.
