A psychologist conducts a one-sample t test to determine whether the average happiness rating of a sample of retirees (M = 7.5, SD = 1.2, n = 40) is different from the general population’s average happiness rating of 7.0 (on a scale from 1 to 10). The results are: t(39) = 1.82, p = .074, d = 0.29.Based on these results, what should the researcher conclude about statistical significance?
