Question: Now, run a linear regression (i.e. only using education as a predictor, not education squared) that only uses the data for men with 0-12 years
Now, run a linear regression (i.e. only using education as a predictor, not education squared) that only uses the data for men with 0-12 years of schooling. Report the coefficient on education. Does this coefficient look meaningfully different from the one you get when you include the full range of data?
Use this new regression to predict the income of someone with 16 years of education. Is this prediction accurate? Discuss: why do you think this prediction is (or is not) accurate?
