Question: For each scenario, (a) state the research question, and (b) select the appropriate statistical test.

Though most of the people to whom I have taught statistics have been psychology majors, my impression is that some of my best statistics students have been non-psychology majors. And, contrary to the idea that men are better at math than women, I've been struck by how well women do in my stats class. So, I've decided to investigate how gender and/or major affect performance in my statistics class. I obtain a random sample of students from the hundreds to whom I have taught statistics and for each person I note three facts: (a) his or her gender, (b) whether he or she was a- psychology major, and (c) his or her total -accumulated points in my class.
