Question
You are asked to estimate the model wage=B1+B2 EDU+ B3 EDU? where wage is the hourly wage ($) and EDU is the
number of years of education. OLS results from a sample of 1000 university graduates are reported below:
Wage=9.79-1.20 EDU+0.089 EDU2; R-square%-D0.23
se (2.67) (0.40)
(0.09)
Test the hypothesis that the expected effect of an extra year of education on hourly wage of an individual with 12
years of education is $1 against the alternative that it is less than $1 at 5% significance level (show all work). You are
given the se(b2+2"b3 EDU)=D 0.045
