DATAfile: Stroke 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.

Use x, for age, x, for blood pressure, and x, for whether a person is a smoker. (Round your constant term to one decimal place and coefficients to three decimal places.) Submil
