Answer #1

Sarah should use Regression Analysis to understand the contribution of daily calorie intake, weight, weekly amount of cardiovascular exercise, and smoking history on heart disease because these predictors are expected to be linearly related to heart disease but the scale of measurement for the dependent variable heart disease should be continuous so that we can measure the effect of each of these predictors on heart disease.
