NO.PZ2018062016000119问题如下whiof the following statement is most likely correct?A.95% confinlevel means thwe have 95% probability to rejeH0B.Test statistic is calculatewith the population taC.Criticvalue is terminethe significanlevel C is correct. 95% confinlevel means thwe have 95% probability not to rejeH0. Test statistic is calculatewith the sample tconfinlevel的定义在哪里出现的?我们可以把confinlevel当作significant level的反面吗?
