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.

怎么判断 原假设和Ha? 谢谢

同学你好，

如果题目问某个X的系数是不是significant，意思就是原假设为这个系数等于0，例如 H0：b1=0.

如何建立原假设和备择假设的考点在二级不怎么考。

Ha 一般是题目研究的东西 对吗? 谢谢。
