问题如下:
A hypothesis test for a normally-distributed population at a 0.05 significance level implies a:
选项:
A.
95% probability of rejecting a true null hypothesis.
B.
95% probability of a Type I error for a two-tailed test.
C.
5% rejection region in a tail of the distribution for a one-tailed test.
解释:
C is correct.
For a one-tailed hypothesis test, there is a 5% rejection region in one tail of the distribution.
对于单尾的检验(for a one-tailed test),单侧拒绝域是5%。
同样都是95%,单尾是0.05等同于双尾的0.025吗?
