A,B说法都不对,显著性水平就是正确拒绝一个正确假设的概率,显著性水平也应该等于第一类错误。所以AB的说法中的95%,都应该换做5%

NO.PZ2017092702000123 问题如下 A hypothesis test for a normally-stributepopulation a 0.05 significanlevel implies A.95% probability of rejecting a true null hypothesis. B.95% probability of a Type I error for a two-tailetest. C.5% rejection region in a tail of the stribution for a one-tailetest. C is correct. For a one-tailehypothesis test, there is a 5% rejection region in one tail of the stribution.对于单尾的检验(for a one-tailetest),单侧拒绝域是5%。 0.05 significanlevel,不就意味着type I error的发生概率是5%吗?
