问题如下：
which of the following statement is most likely correct?
选项：
A.95% confidence level is that means we have 95% probably reject H0
B.Test statistic is calculated with the population data
C.Critical value is determined by the significantly level
解释：
C is correct. 95% confidence level is that means we have 95% probably not reject H0,test statistic is calculated with the sample data.
B选项，如果使用了总体方差来算xbar的方差，不就是使用了总体数据吗？

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？
