Suppose a researcher estimates the relationship between average earnings (Y) and number of years of education (E), separately for immigrants (I) and native born (N) workers. She obtains the following estimates:

3. 17,, = (1N + BNEN = 35,000 + 3,0001?\" 17, = a, + mi, = 25,000 + 1,5005, Suppose that native born workers have, on average, 12 years of education (E N = 12) and immigrant workers have 14 (E I = 14). What 1s the average earnings of native born workers? The average earnings of immigrants? What 1s the raw earnings gap between native born workers and immigrants?
