PROBLEM 2: The researcher conducted an experiment to determine whether chocolate cake has an effect on the aggression level of preschool children. He employed two different groups. One group ate chocolate cake while the other group ate an ordinary cake without chocolate content. He wanted to test the hypothesis at 0.05 level of significance. The following results were gathered: AGGRESSION LEVEL OF THOSE AGGRESSION LEVEL OF THOSE WHO ATE CHOCOLATE CAKE WHO ATE AN ORDINARY CAKE 1.22 1.23 3.45 2.55 1.40 3.50 2.30 1.20 3.50 1.20 2.40 3.20 1.30 2.20 4.00 1.22 3.50 3.40 2.30 1.50
