问一道题：NO.PZ2015120604000143 [ CFA I ]

NO.PZ2015120604000143 问题如下 Here is a table shows a set of tPeter sets up a null hypothesis--- H0: μ=8.5. If Peter fail to rejethe null hypothesis 10% significanlevel, whiof the following P value is most appropriate? A.P value=12% B.P value=5% C.P value=3% A is correct. If P value is bigger ththe calculatetest statistithen Peter will fail to rejethe null hypothesis.P value=12%, Significanlevel = 10%, fail to rejeH0. p越小，越接受原假设。即，fail to reject。为什么是大于拒绝yu 10%啊

    请问老师，≠难道不应该是双尾吗，双尾显著域应该是5%吧？P应该是大于5%而不是大于10%。这样理解对吗

    不是特别理解，可以详细一下吗？

    怎样计算出来的？
