An African American sociology student wants to test the hypothesis that Affirmative Action has helped alleviate racial discrimination on college campuses in the United States. The student does not have access to funds to pay interviewers or to use most other methods of gathering data so the student decides to use existing statistics as his source of data.

explain what information this student will need to collect in order to test the hypothesis. Provide a link to at least one source(credible/apa of existing statistics that would have some data that the student could use to test the hypothesis.
