B is incorrect because a z-statistic equal to the rejection point of 1.645 is not statistically significant and would not support rejecting the null hypothesis.【释义】C是正确的。当p值小于α时,可以拒绝假设,α=0.05,因此p应该小于0.05,z大于1.645,。
Thus, the power of a hypothesis test is the probability of not committing a Type II error.【释义】检测力度(power of a test)是当原假设为为假时,拒绝假设的可能性。第二类错误是原假设为假但没有被拒绝。因此检测力度就是不犯第二类错误的概率。
