(5) Consider the model

where totcoll is the total years of college education

(i) What is the predicted log wage for a woman with 2 years of total college?

(ii) Using the regression, find the value of totcoll such that the predicted values of

log(wage) are the same for men and women.

(iii) Are the returns to college education for women statistically different from those of

men? Perform a two-sided hypothesis test at the 5% level.
