问题如下：

which of the following statement is most likely correct?

选项：

A.

95% confidence level means that we have 95% probability to reject H0

B.

Test statistic is calculated with the population data

C.

Critical value is determined by the significance level

解释：

C is correct. 95% confidence level means that we have 95% probability not to reject H0. Test statistic is calculated with the sample data.

confidence level的定义在哪里出现的？我们可以把confidence level当作significant level的反面吗？

嗨，爱思考的PZer你好：


1）confidence level就是confidence interval；

2）我们可以把confidence level当作significant level的反面吗？-----可以，confidence level=1-significance level
