NO.PZ2018062016000120 问题如下 whiof the following statement is most likely correct? A.Rejethe null hypothesis if the B.Accept the null hypothesis if the C.Rejethe null hypothesis if the A is correct, accorng to the cision rule, rejethe null hypothesis if the |test statisti>|criticvalue|, anwe conly scannot rejethe null hypothesis. 是不是应该分情况讨论呀1.如果单尾,H0:μ≤x,Haμ>x,当test stiastic>criticvalue的时候,rejeH0。 2. 如果单尾,H0:μ≥x,Haμ<x,当test stiastic<criticvalue的时候,rejeH0。那这样是不是A和C都正确
