问题如下：

6. For the analysis run by Batten, which of the following is an incorrect conclusion from the regression output?

选项：

A.

The estimated intercept coefficient from Batten’s regression is statistically significant at the 0.05 level.

B.

In the month after the CPIENG declines, Stellar’s common stock is expected to exhibit a positive return.

C.

Viewed in combination, the slope and intercept coefficients from Batten’s regression are not statistically significant at the 0.05 level.

解释：

C is correct.

C is the correct response, because it is a false statement. The slope and intercept are both statistically significant.

同学你好，

需要掌握正态分布下置信区间的一组关键值。这组值考试的时候是会以某种形式给出的，但是如果记忆住了可以节省时间（如不需重新自行查表）。

90%置信区间：±1.645-----对应单尾面积5%；

95%置信区间：±1.96-------对应单尾面积2.5%；

99%置信区间：±2.58-------对应单尾面积0.5%；

t分布的关键值只能查表。

NO.PZ201512020300000206 请一下b，题目说“in the month after the CPIENG clines” 所以指的是在自变量下降的后一年return的变化，由于这一年是cline，所以return是positive，考虑到均值复归，下一年应该是negative，为什么不能这样理解？
