Econ 3210 Midterm, Page 6 of 12 October, 2015 (c) (10 marks) Given your answer in part (b), calculate the slope coefficient from a regression of IQ on years of education (61 below): 1Q = do + 61 years of education (d) (5 marks) Interpret the R2 in column (2).Econ 3210 Midterm, Page 5 of 12 October, 2015 2. Below is a table of regression output produced in R. The table contains two regressions. The first regression, reported in column (1), is a simple regression of log hourly wages on years of education. The second column contains results for a regression of log hourly wages on years of education and IQ (score on an 1Q exam). The numbers listed in the table are the estimated coefficients with standard errors listed under the estimate in parenthesis.
