选项：
老师好，请问为什么不选B
A. 
B. 
C. 
解释：
NO.PZ201512020300000106 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. 如标题这道题中的原假设是什么？拒绝原假设代表显著还是不显著？c中的for F ant 是什么意思？
NO.PZ201512020300000106 请问老师，此题中anova 表里significanF就是F检验的P-value 是吗；另外我们说p-value小于a时拒绝原假设，此题的a是不是就是0.05呢

P value=0，怎么样都小于5%的1.96criticvalue啊，所以应该接受原假设，not significant啊，应该选B啊
significant 5%? 1.这里的原假设是二者关系=0 ？ 2.然后在5% 的范围内是接受域， 就是原假设在接受域是不显著的？ 3。=0是否意味着x和Y无关？ 4.如果是接受就是 not significant , 如果拒绝就是significant？ 5.是不是所有significant都是检验x和Y是否为0 接受就是not significant？
老师，您好！这道题c为什么要看p-valve for F？F-statistic不是等于t的平方吗？
