Do angry people have more heart disease? Which of the following techniques should we use to find the answer? A) Calculate the total number of people who have CHD and then find the relative proportions of such people that also have a high anger level. B) Calculate the conditional distribution of anger level given CHD. C) Calculate the total number of people who have CHD and compare this to the total number of people who have a high anger level. D) Calculate the total number of people at each anger level, and then for each anger level, find the relative proportion of people who have CHD.

5.32 (EX) Do angry people have more heart disease? 1/4: People who get angry easily tend to have more heart disease. That's the conclusion of a study that followed a random sample of 12,986 people from three locations for about four years. All subjects were free of heart disease at the beginning of the study. The subjects took the Spielberger Trait Anger Scale test, which measures how prone a person is to sudden anger. Here are data for the 8474 people in the sample who had normal blood pressure. CHD stands for coronary heart disease. This includes people who had heart attacks and those who needed medical treatment for heart disease. Low anger Moderate anger High anger Total 27 190 606 8284 633 8474 CHD 53 110 No CHD 3057 4621 Total 3110 4731 Do these data support the study's conclusion about the relationship between anger and heart disease? Which of the following statements best describes the question we are trying to answer? O Would people who suffer from heart disease benifit from learning to control their anger? O Is it possible to reduce heart disease by managing stress and anger levels? O After contracting heart disease, do people get angry more easily? Do people who tend to get angry easily also suffer from more heart disease?
