Find the test statistic for this hypothesis test.
(Round to two decimal places as needed.)
Determine the P-value for this hypothesis test.
(Round to three decimal places as needed.)
State the conclusion for this hypothesis test.
O A. Reject H,- There is sufficient evidence at the a = 0.01 level of significance to conclude that p, > H2.
O B. Do not reject Hg. There is not sufficient evidence at the a = 0.01 level of significance to conclude that u, > H2.
O C. Do not reject H,. There is sufficient evidence at the a= 0.01 level of significance to conclude that u, > H2-
O D. Reject Hn. There is not sufficient evidence at the a= 0.01 level of significance to conclude that u, > H2-
(b) The 90% confidence interval about u, - H, is the range from a lower bound of
to an upper bound of
