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 person will have a stroke over the next 10-year period. For the smoker variable, 1 indicates a smoker and 0 indicates a nonsmoker. Risk Age Blood Pressure Smoker 12 57 152 24 67 163 13 58 155 56 86 177 1 28 59 196 51 76 189 1 18 56 155 1 31 78 120 37 80 135 1 15 78 98 22 71 152 36 70 173 1 15 67 135 1 48 77 209 1 15 60 199 36 82 119 1 8 66 166 34 80 125 1 3 62 117 37 59 207 Using age, blood pressure, and whether a person is a smoker, develop an estimated regression equation that can be used to predict risk. Use x, for age, x, for blood pressure, and x, for whether a person is a smoker. (Round your constant te to one decimal place and coefficients to three decimal places.)
