Espey Jones is examining the relation between the net profit margin
(NPM) of companies, in percent, and their fixed asset turnover (FATO). He
collected a sample of 35 companies for the most recent fiscal year and fit
several different functional forms, settling on the following model:
lnNPMi=b0+b1FATOi
The
results of this estimation are provided in Exhibit 1.
The predicted net profit margin for a company with a fixed asset turnover of 2 times is closest to:
选项：
A.1.1889%
B.1.8043%
C.3.2835%
解释：
The predicted natural log of the net profit margin is
0.5987 + (2 × 0.2951) = 1.1889. The predicted net profit margin is e1.1889
= 3.2835%.
