Identifying individuals with a high risk of Alzheimer’s disease usually involves a long series of cognitive tests. However, researchers have developed a 7-Minute Screen, which is a quick and easy way to accomplish the same goal. The question is whether the 7-Minute Screen is as effective as the complete series of tests. To address this question, Ijuin et al. (2008) administered both tests to a group of patients and compared the results. The following data represent results similar to those obtained in the study:   Patient            7-Minute         Screen Cognitive Tests  A                            3                           11  B                            8                           19  C                          10                           22  D                            8                          20  E                            4                           14  F                            7                           13  G                           4…
