问题如下：
2. Paul Frank is valuing a biotechnology stock with a dividend payout ratio of 0.05, a beta of 2.5, and an expected earnings growth rate of 0.34. The predicted P/E on the basis of the values of the explanatory variables for the company is closest to:
选项：
A.13.200
B.15.138
C.17.158
D.11.308
解释：
B is correct.
考点：Predicted Value of the Dependent Variable
解析：在其他变量保持不变的前提下，当哑变量IND=1时，意味着选取的是生物科技行业股；当哑变量IND=0时，意味着选取的是医疗设备行业股。所以本题中，IND=1。
Y = 4.55+1*7.25+0.05*6+0.34*14.45+2.5*(-0.75) = 15.138
DPO和B不是在5%的情况下不显著吗，为什么在式中还要计算？
