Question 26 of 39 This test: 39 point(s) possible {:93 This question: 1 point(s) possible Submit test Use a t-test to test the claim about the population mean u at the given level of significance or using the given sample statistics. Assume the population is normally distributed. Claim: u 2 8100; a = 0.10 Sample statistics: it: 7900, s = 440, n = 20 The standardized test statistic is . (Round to two decimal places as needed.) What is the P-value'? P = (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. Choose the correct answer below. (:3 A. Fail to reject H0. At the 10% level of signicance, there is not enough evidence to reject the claim. C) B. Reject H0. At the 10% level of significance, there is not enough evidence to reject the claim. (:3 C. Reject H0. At the 10% level of significance, there is enough evidence to reject the claim. C? D. Fail to reject HO. At the 10% level of signicance, there is enough evidence to reject the claim.
