选项：

A.

B.

C.

解释：


1. significance F 不是说的是pvalue？ p小于0.05所以拒绝？不对吗？

2。解释里的F statisitic 4.161 直接跟alpha=0.05比较是不是不对呀？

为什么？

同学你好，F检验相关知识如下：

这道题确实是拒绝原假设，但F检验得到的结论是，至少有一个自变量的系数不等于0，也就是说至少有一个自变量是显著的，所以C正确。

并且，答案并没有那F统计量的值跟0.05比较，只是说F统计量在α=0.05时是显著的，没有问题。

Baseon Exhibit 1, Varn’s best answer to Quinni’s question about the F-statistic is: both inpennt variables are significant the 0.05 level. neither inpennt variable is significant the 0.05 level. least one inpennt variable is significant the 0.05 level. C is correct. Exhibit 1 incates ththe F-statistic of 4.161 is significant the 0.05 level. A significant F-statistic means least one of the inpennt variables is significant. 如题

A significant F-statistic means least one of the inpennt variables is significant. 这里F值显著更准确的应该是all coefficients are joint significant the 0.05 level吗？

F-test的H0是所有b都等于0，现在Pvalue非常小所以证明拒绝原假设，所以说b不等于0，那为什么不选A呢？
