An experimenter was interested in the effects of gender and arousal on a measure of aggressive strategies. Your data represent the number of aggressive responses for male and female subjects (B1 and B2 respectively) across three conditions of arousal: low, medium, and high (A1, A2, and A3, respectively). In your response to the questions, use the data set assigned to you by the teaching assistant.
