NO.PZ2018062001000014问题如下All else equal, a larger significant level incates:A.A higher probability of type I error antype II error.B.A higher probability of type I error anlower probability of type II error.C.A lower probability of type I error anhigher probability of type II error.B is correct.The significant level of a test is the probability of a Type I error. Therefore a larger significant level means a higher probability of Type I error.Type II error occurs when we fail to rejea false null hypothesis. It will smaller if significant level of a test is larger, all else equal.我们越容易去拒绝原假设，也就意味着我们越不容易去接受一个错误的原假设。这句话怎么理解啊，可以举一个例子吗？

significanlevel 越大说明 α 越大，在其他相等的情况下，不就意味着x-μ/x/根号下n，n变大了？ n变大了，不是typeI 和type II 都变下？
不懂呀，这道题目详细讲解一下吧，老师
