No.PZ2018062016000119 (选择题) C选项

  1. CFA I
  2. Quantitative

NO.PZ2018062016000119

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.

老师上课的时候说critical value是由1、选择t分布还是z分布；2、⍺；3、单尾或双尾

可以就像C选项那样片面地说critical value是由其中某一个因素决定的吗？

同学你好，

如果把提到的这些因素都说上会更为严谨一些。但本题要选“most likely correct”，A、B选项都有明显错误，综合考虑和排除后选择C选项。
