A statistical program is recommended.

A 10-year study conducted by the American Heart Association provided data on how age, blood pressure, and smoking relate to the risk of strokes. Data from a portion of this study follow. Risk is interpreted as the probability (times 100) that a person will have a stroke over the next 10-year period. For the smoker variable, 1 indicates a smoker and 0 indicates a nonsmoker.

Using age, blood pressure, and whether a person is a smoker, develop an estimated regression equation that can be used to predict risk. Usex₁for age,x₂for blood pressure, andx₃for whether a person is a smoker. (Round your constant term to one decimal place and coefficients to three decimal places.)
