A recent 10-year study conducted by a research team at the GreatFalls Medical School was conducted to assess how age, systolicblood pressure, and smoking relate to the risk of strokes. Assumethat the following data are from a portion of this study. Risk isinterpreted as the probability (times 100) that the patient willhave a stroke over the next 10-year period. For the smokingvariable, define a dummy variable with 1 indicating a smoker and 0indicating a nonsmoker.
