Then perform a two-way ANOVA on postquiz heart rate, using the new phobia grouping variable and the quiz conditions (last question easy, moderate, difficult, or impossible) as your two factors.

a. Request a graph of the cell means, and refer to the graph to explain the results of the two-way ANOVA.

b. Test all of the possible pairs of levels for the quiz-condition factor.
