选项：

A.

B.

C.

解释：



题干中的F significant =0.023，因为0.023<0.05，所以是significant at 0.05 level吧？

题干中的F significant 是否是相当于F统计量的P-value？

你的理解是正确的，运用P值就是越小越拒绝， 0.023<0.05 ，所以拒绝原假设，所以至少一个解释变量行得通。

题干中的F significance 就是F统计量的P-value

NO.PZ201709270100000306 问题如下 6. 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？
