18.10 Anger and heart disease. A nonexperimental study looked at whether people who angered easily were more likely to develop coronary heart disease than those who angered less easily. Spielberger anger scale scores were classified into low, moderate, and high categories. Individuals were followed for up to 72 months (median follow-up time: 53 months). Table 18.9 shows cross-tabulated results for acute and fatal coronary incidents. Calculate incidence proportions for each group. Test the association for statistical significance. Report the chi-square statistic, its df, and P-value.
