Analyzing the Relationship Between Anger Levels and Coronary Heart Disease Using Chi-Squared Test

This analysis investigates the correlation between anger levels (low, moderate, high) and the incidence of coronary heart disease (CHD) using the Chi-squared test for independence. The dataset highlights the number of individuals with and without CHD across different anger levels. Expected counts are calculated to compare observed frequencies against expected frequencies, leading to the computation of the p-value. This study aims to draw conclusions about whether higher anger levels are associated with an increased risk of coronary heart disease.
