The document presents the results of two separate chi-square tests examining relationships between variables. The first test found a significant relationship between exercise and heart attacks, with those exercising less likely to have a heart attack. The second test found a significant relationship between being breastfed and overweight status, with those breastfed less likely to be overweight. Both null hypotheses of no relationship between the variables were rejected based on a p-value of less than 0.05.
