A Canadian study measuring depression level in teens (as reported in the Journal of Adolescence, vol. 25, 2002) randomly sampled 112 male teens and 101 female teens, and scored them on a common depression scale (higher score representing more depression). The researchers suspected that the mean depression score for male teens is higher than for female teens, and wanted to check whether data would support this hypothesis. Use StatCrunch to test this hypothesis at the 5% level of significance. (directions) Two-Sample T-Test and CI Sample n Mean Std. Dev. Male 112 7.38 6.95 Female 101 7.15 6.31 What conclusion can you draw from the output? Group of answer choices The data provide sufficient evidence to reject H and to conclude that the mean depression score for male teens is larger than that of female teens. The data provide sufficient evidence to conclude that male and female teens do not differ in mean depression score. The data do not provide sufficient evidence to conclude that the mean depression score of male teens is larger than that of female teens. The data do not provide sufficient evidence to reject H , so we accept it, and conclude that male and female teens do not differ in mean depression score.
