Question
Identifying individuals with a high risk of Alzheimer's disease usually involves a lons 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. A) Compute the Pearson correlation to measure the degree of relationship between the two test scores. B) Is the correlation statistically significant? Use a two-tailed test with a = .01. C) What percentage of variance for the cognitive scores is predicted from the 7-Minute Screen scores?
