问题如下图：
选项：
A. 
B. 
C. 
解释：
1.您好，表格中的检验是检验b1是否为0，二题目中说的是0.05significant level ,0 实在这个区间内，所以接受原假设？
2. 我想问一下F检验=0 能代表什么意思？是说MSR大还是MSE小？
3.为什么c对？
4.是不是一定要同时观察 significant F和t检验的值？

同学你好，
1. 可以看做是检验系数b1是否为0。
2. 5%是显著性水平，我们判断是否要拒绝原假设是通过
1）比较5%显著性水平的临界值和t统计量；2）比较p-value和显著性水平。
并不是说0在这个区间内就不拒绝原假设。
3. 题目表格中的这个Significance F等于0，这里的Significance F其实跟P-value的原理一样，也就是C选项说的p-value for F，其实就相当于是F检验的p-value，可以直接拿这个跟显著性水平α进行比较来得出结论。
4. 当p-value和Significance F小于α时，我们就拒绝原假设，所以说明这个回归方程在5%的显著性水平下是显著的。所以C对。
5. 对于这个题目来说，只有一个自变量的时候，其实用两者其中任意一个来得出结论都是可以的。（因为F检验代表的是所有自变量作为一个整体的检验，对于一元回归来说，跟t检验的结果是一样的。）
NO.PZ2015120204000006 No, because the p-values of the intercept anslope are less th0.05. Yes, because the p-values for F ant for the slope coefficient are less th0.05. C is correct. The p-value reflects the strength of the relationship between the two variables. In this case the p-value is less th0.05, anthus the regression of the ratio of cash flow fromoperations to sales on the ratio of net income to sales is significant the 5 percent level. 解析只说了p小于0.05
NO.PZ2015120204000006 The p-value reflects the strength of the relationship between the two variables. 这句话不理解。针对题目最后的问题，为什么是看p来判断呢
No, because the p-values of the intercept anslope are less th0.05. Yes, because the p-values for F ant for the slope coefficient are less th0.05. C is correct. The p-value reflects the strength of the relationship between the two variables. In this case the p-value is less th0.05, anthus the regression of the ratio of cash flow fromoperations to sales on the ratio of net income to sales is significant the 5 percent level. 这道题的假设检验中，原假设应该是什么？

问两个问题。1,B为什么错了？？2，这道题目不是一元回归吗，为什么C还要用F检验，不应该就T检验就够了吗？？
