问题如下:
Which of the following items describes the probability of rejecting the null when it is false?
选项:
A.level of significance.
B.power of a test.
C.p-value.
解释:
B is correct. Whereas the significance level of a test is the probability of incorrectly rejecting the null, the power of a test is the probability of correctly rejecting the null.
由于Type II error是当原假设为假的时候,没有拒绝原假设的概率。所以从描述上可以看出,Type II error+ power of test=1。
还是不太理解这句
