Exercises 4.10 and 4.69 presented data on grumpy old men and heart disease. In Chapter 4, the goal was to determine if there was a relationship between the two variables. A onetailed test may also make sense. We might hypothesize that if there is a difference in the probability of developing heart disease for men with no anger and men with lots of anger, the latter group would have a higher probability. Minitab output for testing this claim follows. Note that p1 is the probability of developing heart disease for men with no anger and p2 is the probability of developing heart disease for men with the most anger.
