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. Assume that the following data are from a portion of this study, Risk is interpreted as the probability (times 100) that the patient will have a struke over the next 10 year pernod. Risk Age Pressure Smoker 12 47 163 Risk Age Pressure Smoker 12 57 152 0 24 24 67 163 0 13 58 155 0 56 86 177 1 28 59 196 0 51 76 189 1 18 56 155 1 31 78 120 0 37 80 135 1 15 78 98 0 22 71 152 0 36 70 173 1 15 67 135 1 48 77 209 1 15 60 199 0 36 32 82 119 1 8 66 166 0 34 00 80 125 1 3 62 117 0 37 59 207 1 (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 represent age, x, represent blood pressure, x, represent whether the person is a smoker, and y represent risk. For the smoking variable, define a dumm variable with 1 indicating a smoker and 0 indicating a nonsmoker. Round your constant term to one decimal place and coefficients to two decimal places.) (b) Is smoking a significant factor in the risk of a stroke? Explain. Use a -0.05. State the null and alternative hypotheses 40-0 OH B-0 HO O Ho0 OH F 20 HP < 0 Find the value of the test statistic.
