问题如下:
Based on the regression, if the CPIENG decreases by 1.0%, the expected return on Stellar common stock during the next period is closest to:
选项:
A.0.0073 (0.73%) B.0.0138 (1.38%) C.0.0203 (2.03%)解释:
C is correct. From the regression equation, Expected return = 0.0138 + (-0.6486 x -0.01) = 0.0138 + 0.006486 = 0.0203, or 2.03%.
记得之前有一道题乘1%的时候,是直接抛掉百分号乘1的。这里却又把1%转化为0.01。所以应不应该将百分号转化呢,还是直接抛掉呢?
