解释:
Type 2 error has a positive effect with the sample size?
sample size越大,Type 1&Type 2 error不是应该越小吗?不能理解?
NO.PZ2018062016000130 问题如下 Whiof the following statements on the power of a test is most correct? A.The power of a test is the probability of making a Type I error. B.The power of a test is the probability of not making a Type II error. C.The power of a test ha negative effewith the sample size. B is correct. The power of a hypothesis test is the probability of not making a Type II error anit ha positive effewith the sample size. 在哪个视频中呢 没听到呢

NO.PZ2018062016000130 表格中的significanlevel = P 和 power of test =1-P, 这两个P不是同一个数据吧? Type I error =P1, Type II error= P2 是这么理解吗?
The power of a test is the probability of not making a Type II error. The power of a test ha negative effewith the sample size. B is correct. The power of a hypothesis test is the probability of not making a Type II error anit ha positive effewith the sample size.C是什么意思?怎么理解?我理解的是当样本规模增大,出现1.2的错误会降低,所以negative effect是对的
The power of a test is the probability of not making a Type II error. The power of a test ha negative effewith the sample size. B is correct. The power of a hypothesis test is the probability of not making a Type II error anit ha positive effewith the sample size.是在不明白几个的意思
