A developmental psychologist studies moral awareness in male and female adolescents. Casual observation suggests that girls develop moral awareness earlier than boys, though most published research contains only male participants. A standard measure of moral awareness, on validated using only a male sample, has a mu = 72 and sigma = 18. The psychologist administers the measure to 58 13-year-old girls, whose mean scores was M = 76. Test the hypothesis that the moral awareness of girls is different from males. Conduct a complete hypothesis test using alpha = .01.
