Use technology and a t-test to test the claim about the population mean mu at the given level of significance alpha using the given sample statistics. Assume the population is normally distributed. Claim: mu greater than71; alpha equals0.05 Sample statistics: x overbar equals73.9, sequals 3.7, nequals 25 What are the null and alternative hypotheses? Choose the correct answer below. A. H0: mu equals71HA: mu not equals71 B. H0: mu less than or equals71HA: mu greater than71 C. H0: mu greater than or equals71HA: mu less than71 D. H0: mu not equals71 HA: mu equals71 What is the value of the standardized test statistic? The standardized test statistic is nothing . (Round to two decimal places as needed.) What is the P-value of the test statistic?P-valueequals nothing (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. A. Reject Upper H 0 . There is enough evidence to support the claim. B. Fail to reject Upper H 0 . There is not enough evidence to support the claim. C. Reject Upper H 0 . There is not enough evidence to support the claim. D. Fail to reject Upper H 0 . There is enough evidence to support the claim.
