问题如下：
3. Based on the regression, which used data in decimal form, if the CPIENG decreases by 1.0 percent, what is the expected return on Stellar common
stock during the next period?
选项：
A.0.0073 (0.73 percent).
B.0.0138 (1.38 percent).
C.0.0203 (2.03 percent).
解释：
C is correct.
From the regression equation, Expected return = 0.0138 + -0.6486(-0.01) = 0.0138 + 0.006486 = 0.0203, or 2.03 percent.
“the CPIENG decreases by 1.0 percent”的意思应该是CPIENG减少了1%吧？答案的算法怎么看着是CPIENG现在的值就是1%呢?
