Use the data in WAGE1.RAW for this exercise.
(i) Use equation (7.18) to estimate the gender differential when educ = 12.5. Compare this with the estimated differential when educ = 0.
(ii) Run the regression used to obtain (7.18), but with female_(educ _ 12.5) replacing female •educ. How do you interpret the coefficient on female now
(iii) Is the coefficient on female in part (ii) statistically significant Compare this with (7.18) and comment.
