Use a t-test to test the claim about the population mean p at the given level of significance a using the given sample statistics. Assume the population is normally distributed. Claim: p#27; ®=0.01 Sample statistics: x=27.7, s=4.2, n=11 What are the null and alternative hypotheses? Choose the correct answer below. ¥ Hyp=27 Hy p227 Hop#27 Hop<27 Ho p<27 Ho n#27 Hyop>27 Hyop=27 What is the value of the standardized test statistic? The standardized test statisticis 0.55 . (Round to two decimal places as needed.) What is the P-value of the test statistic? P-value = 0.593 (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Fail to reject Hy. There is enough evidence to support the claim. Reject Hy. There is not enough evidence to support the claim. ¥ Fail to reject Hp. There is not enough evidence to support the claim. Reject Hy. There is enough evidence to support the claim.
