请问这道题需要查表吗？如果需要，哪里查表？谢谢！
NO.PZ2015120204000012 In the month after the CPIENG clines, Stellar’s common stois expecteto exhibit a positive return. Viewein combination, the slope anintercept coefficients from Batten’s regression are not statistically significant the 0.05 level. C is correct. C is the correresponse, because it is a false statement. The slope anintercept are both statistically significant.可以证明Y变化量大于零，并不能说明Y大于零啊。您看我理解哪里有问题。谢谢
NO.PZ2015120204000012 B可以一下吗？
品职老师，请问这道题是不是可以这样理解。 首先，1) 确认假设H0=sample b1=0 2) 计算confinlevel: sample b1土t *Sb sample = -0.6486 土 1.96*0.2818 = （-1.2009， -0.096），因为样本很大假设服从Z分布，95%对应1.96. 3）计算t统计量=-2.301632，因为落在拒绝域，所以拒绝原假设，所以可以得出自变量对因变量显著影响。
A为什么是对的呢
In the month after the CPIENG clines, Stellar’s common stois expecteto exhibit a positive return. Viewein combination, the slope anintercept coefficients from Batten’s regression are not statistically significant the 0.05 level. C is correct. C is the correresponse, because it is a false statement. The slope anintercept are both statistically significant. Intercept为啥是significant？ T值3.0275挺大的啊
