Software companies have developed computer programs that they claim will help senior citizens remain active. A consumer advocacy organization conducted a study designed to evaluate two competing software applications claimed to train the brain of this population. Thirty participants over the age of 65 were recruited into this study, with half given application ("App") A, and the other, App B. They were taught how to use the software and instructed to use it for at least 30 minutes a day for 2 months. After 2 months the memory performance of both groups was measured. For this scenario, you may assume that a score of zero (0) in memory means that nothing was remembered, and therefore 0 is not arbitrary.
