A kinesiologist and a psychologist collaborated on a study to investigate the relationship between exercise and mental health. They obtained a random sample of 1,002 American men. They administered an interval- level mental health scale to each man and measured how many minutes of aerobic exercise each got per week. (On both measures, higher scores are better.) No assumptions were violated for the Pearson r and they found r(1,000) = .36, p < .05. r² was 12.96% and the 95% confidence interval ranged from .31 to .41. Complete a four-point interpretation.
