DATAle: Stroke You may need to use the appropriate technology to answer this question. 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 he probability (times 100) that the patient will have a stroke over the next loiyear period. For the smoking variable, define a dummy variable with 1. indicating a smoker and 0 indicating a nonsmoker. Systolic Blood Smoker Pressure 152 No 163 No 155 No 177 Yes 196 No 189 Yes 155 Yes 120 No 135 Yes 98 No 152 No 173 Yes 135 Yes 209 Yes 199 No 119 Yes 8 66 166 No 34 80 125 Yes 3 62 117 No 37 59 207 Yes (a) Develop an estimated regression equation that relates risk of a stroke to the person's age, blood pressure, and whether the person is a smoker. (Let x1 represent age, x2 represent blood pressure, x3 represent whether the person is a smoker, and y represent risk. Round your numerical values to four decimal places.) y : 91.T595 + 1.0767x1 + 0.2518x2 + 8.739x3 X (c) What is the probability of a stroke over the next 10 years for Art Speen, a 65*yeariold smoker who has a systolic blood pressure of 185? (Round your answer to four decimal places.) ,3714 x (d) An insurance company will only sell its Select policy to people for whom the probability ofa stroke in the next 10 years is less than 0.01. Ifa smoker with a systolic blood pressure of 205 applies for a Select policy, under what condition will the company sell him the policy if it adheres to this standard? (Round your answer to two decimal places.) This person must be no more than 24.25 X years old to qualify for the Select policy
