A recent 10-year study conducted by a research team at the Great Falls Medical School was conducted to assess how age,
systolic blood pressure, and smoking relate to the risk of strokes. Assume that the following data are from a portion of this
study. Risk is interpreted as the probability (times 100) that the patient will have a stroke over the next 10-year period. For
the smoking variable, define a dummy variable with 1 indicating a smoker and O indicating a nonsmoker.
Develop an estimated multiple regression equation that relates risk of stroke to the person's age, systolic blood pressure,
and whether the person is a smoker. Save the standardized residuals and create the normal probability plot and residual
plots.
