The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject He when the level of significance is (a) a = 0.01, (b) a = 0.05, and (C) a = 0.10. P = 0.0695 (a) Do you reject or fail to reject He at the 0.01 level of significance? O A. Fail to reject H, because the P-value, 0.0695, is greater than a = 0.01. O B. Fail to reject H, because the P-value, 0.0695,...
