Use 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 than or equals8300 ; alpha equals0.10 Sample statistics: x overbar equals8000 , sequals 460 , nequals 23 What are the null and alternative hypotheses? A. H0: mu equals8300 Ha: mu not equals8300 B. H0: mu greater than or equals8300 Ha: mu less than8300 C. H0: mu less than or equals8300 Ha: mu greater than8300 D. H0: mu not equals8300 Ha: mu equals8300 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? Pequals 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 . At the 10 % level of significance, there is enough evidence to reject the claim. B. Fail to reject Upper H 0 . At the 10 % level of significance, there is enough evidence to reject the claim. C. Reject Upper H 0 . At the 10 % level of significance, there is not enough evidence to reject the claim. D. Fail to reject Upper H 0 . At the 10 % level of significance, there is not enough evidence to reject the claim.
