Question: A researcher wants to know whether men and women hold equally negative views of working mothers. He uses a questionnaire for which higher scores indicate more disapproval of mothers who work outside the home. His sample of 21 women are found to have a mean score of M = 2.39 with SS = 1.04; his sample of 21 men have a mean score of M = 3.97 with SS = 5. Do these data provide sufficient evidence to conclude that men and women differ in their negative attitudes toward working mothers at the p < .01 level?
