Correct Answer
Incorrect Answer

There are 2 ways to solve this question:

(1) Calculate the number of unemployed people with a Bachelor's degree and then subtract the number of unemployed people with a Master's degree to arrive at the correct answer:

(2) Calculate the difference in the unemployment rate between people with a Bachelor's degree and people with a Master's degree and then multiply by the total number of the eligible workforce: (0.05-0.04)*5,000,000= 50,000.

* Note that option 2 is a viable option only under the assumption that the data was extracted from the same population.
