Answer:
a. The annual rate of return associated with the 16th year of education is:
9.1%
b. The actual return of return to the 16th year of schooling is more than 9.1%.
Explanation:
a) Data and Calculations:
Average income for people with 15 years of schooling = $60,000
Average income for people with 16 years of schooling = $66,000
Income associated with the 16th year of education = $6,000 (66,000 - 60,000)
Annual rate of return with the 16th year of education = $6,000/$66,000 * 100 = 9.1%
