This experiment consisted of graduates students given either a medium-sized 17-ounce bowls or large-sized 34-ounce bowls. Each student was invited to take as much of four different flavors of ice cream as he or she wanted. The size of the scoop also varied. One held two ounces and the other held three ounces. The students were asked to fill out a survey; while doing so, the amount of ice cream was measured and recorded. Is there sufficient evidence to conclude that either the bowl size or the scoop size or some interaction affected the amount of ice cream?
