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 Ho There is sufficient evidence at the a = 0.10 level of significance to conclude that u, > H2
O B. Do not reject Ho. There is not sufficient evidence at the a = 0.10 level of significance to conclude that u > H2
O C. Do not reject Ho. There is sufficient evidence at the a= 0.10 level of significance to conclude that u, > H2
O D. Reject Ho. There is not sufficient evidence at the a= 0.10 level of significance to conclude that u, >2
