Researchers conducted a study to compare the effectiveness of two pain medications on patients who had been complaining of a certain kind of joint pain. They were interested in the difference in the proportions of patients for who these medications were effective. They gave the medication A to a random sample of 71 patients, and gave medication B to another sample of 66 patients.
