Heart and Estrogen/Progestin Study Data for Questions 5-7 Data from the Heart and Estrogeanrogestin Study (HERS) will be used in the following 4 questions HERS was a clinical trial of hormone therapy (HT) for the prevention of recurrent heart attacks and death among post-menopausal women with existing coronary heart disease (Holley et al. 1998). Women were randomized to a hormone therapy intervention and placebo group. The subset of the data and variables in HERS trial to be used are: Age in years (age) Body Mass index (kg/m2) (BMI) Fasting glucose (mg/dL) (glucose) LDL cholesterol level (mg/LIL) (LDL) Any current alcohol gnumeric (drinkanx: 1 = yes, 0 = no) Exercise at least 3 times per week (exercise: 1 = yes, 0 = no Randomization (HT: 1 = hormone therapy, 0 = placebo) Comparative ("compared to other women your age\") physical activity (Rhysact: 1 = much less active 2 = somewhat less active, 3 = ab out as active, 4 = somewhat more active, 5 = much more active) Statin use, a drug prescribed to lowers LDL cholesterol (Statins: 1 = yes, 0 = no) Diabetes (diabetes: 1 = yes, 0 = no) Q5 Compare Glucose Levels Across Exercise Status (10 Points) Using the 1% dataset, assess if LDL cholesterol levels for women who exercise 3 times per week are 10wer than those who do not exercise 3 times per week while controlling for BMI, glucose levels, age, and statins usage. Cholesterol levels and glucose metabolism are closely related. Having elevated blood glucose levels poses a risk of higher cholesterol. Obesity is also tied to cholesterol. Statins are a popular drug prescribed to lower LDL cholesterol. [4 points] Conduct a multiple regression based t-test in R, use a = 0.05 for the type I error, to carry out the assessment. Use results from the R output of summargg) of a EU command. Interpret the conclusion of your test in the context of the assessment.
