A team of researchers examines the time spent in REM sleep and in each of the NREM stages among a large sample of adults ranging in age from 18 to 70 years old. The researchers compute three correlation coefficients: Correlation A, between participant age and total time spent in NREM Stages 1 and 2; Correlation B, between participant age and total time spent in REM sleep; and, finally, Correlation C, between participant age and total time spent in NREM Stages 3 and 4. Of these correlations, which should be the weakest? Which should be the strongest? This makes no sense - (Stages 1-4) are collectively called nonREM sleep, or NREM so Stages 3 and 4 being is wrong.
