Use the following information for questions:
A study done by the Center for Academic Integrity at Rutgers University surveyed 2116 students at 21 colleges and universities. Some of the schools had an "honor code"and others did not. Of the students at schools with an honor code, 7% reported having plagiarized a paper via the Internet, while at schools with no honor code, 13% did so. (Sacramento Bee, Feb 29, 2000, D1.)
-For this study, the relative risk of a student having plagiarized a paper via the Internet at a school with no honor code, compared to a school with an honor code is:
A) 13/7 = 1.857
B) 7/13 = 0.538
C) 13/87 = 0.149
D) 87/13 = 6.692

The relative risk is calculated by dividing the risk (probability) in the group without the honor code (13%) by the risk in the group with the honor code (7%), which equals 13/7 = 1.857. This indicates that students at schools without an honor code are about 1.857 times more likely to plagiarize a paper via the Internet compared to those at schools with an honor code.
