Extracted text: Doctors developed an intensive intervention program for obese patients with heart disease. Subjects with a BMI of 30 kg/m² or more, with heart disease were assigned to a three-month lifestyle change of diet and exercise. Patients' Left Ventricle Ejection Fraction (LVEF) are measured before and after intervention, A normal heart's ejection fraction may be between 50 and 70 percent, higher numbers indicate a healthier heart. Assume LVEF's are normally distributed.
