问题如下:
Which of the following descriptions is the least accurate about hypothesis testing?
选项:
A. A Type II error refers to accept the null when it is false.
B. A one-tailed test with a significance level of 1% has z-critical values of 2.58.
C. One minus the probability of a Type II error equals the power of test .
解释:
B is correct.
A one-tailed test with a significance level of 1% has z-critical values of 2.33
所以这个是根据置信区间99%这个数字去查表,倒推出的2.33,这么个意思吗?
