问题如下图:
选项:
A.
B.
C.
老师P value 和 level of significant 有什么区别
解释:
1-P 是指再原假设错误的情况下的条件概率,而题干中没有指出原假设错误,因此,Not making Type II error,应包含 原假设正确的情况,和原假设错误时Power of test 的情况。请老师讲评,是不是提出的有问题?
the probability of not making a Type II error. unchangeincreasing a small sample size. B is correct. The power of a hypothesis test is the probability of correctly rejecting the null when it is false. Failing to rejethe null when it is false is a Type II error. Thus, the power of a hypothesis test is the probability of not committing a Type II error.不犯第二种错误是不是也可能犯第一种错误,没有说假设的前提条件一样啊
如果把B改成 不犯I型错误的概率,对吗?
A应该也对吧,正确决绝错误的假设不也属于level of significance
