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:
InNPMi = 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：
C is correct. The predicted natural log of the net profit margin is 0.5987 + (2 x 0.2951) = 1.1889. The predicted net profit margin is e1.1889 = 3.2835%.
求到1.1889，后面步骤不明白
