请问p-value不管单位双尾都是直接和significance level比吗?

问题如下:

2. At a significance level of 1%, which of the following is the best interpretation of the regression coefficients with regard to explaining ROE?

选项:

A.

ESG is significant, but tenure is not.

B.

Tenure is significant, but ESG is not.

C.

Neither ESG nor tenure is significant.

解释:

C is correct. The t-statistic for tenure is 2.308, indicating significance at the 0.027 level but not the 0.01 level. The t-statistic for ESG is 1.201, with a p-value of 0.238, which means we fail to reject the null hypothesis for ESG at the 0.01 significance level.

下次碰到这种题目的问法,也是直接比较即可么

同学你好,

对的。p-value不需要考虑单双尾的问题。

Ha 一般是题目研究的东西 对吗? 谢谢。
