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 the probability (times 100] that the patient will have a stroke over the next 10-year period. For the smoking variable, define a dummy variable with 1 Indicating a smoker and O Indicating a nonsmoker Systolic Risk Age Blood Smoker Pressure 10 58 152 Yes 25 65 163 No 12 58 155 No 57 177 Yes 28 59 196 50 189 Yes 17 56 155 Yes 32 78 120 No 37 135 No 15 78 No 22 71 152 No 36 70 173 Yes 15 67 135 Yes 46 77 209 Yes 15 199 No 119 Yes 66 166 No 34 80 125 No 62 117 No 38 59 209 Yes(a) Develop an estimated multiple regression equation that relates risk of a stroke to the person's age, systolic blood pressure, and whether the person is a smoker Let ij represent the person's age. Let xz represent the person's systolic blood pressure. Let ag represent whether the person is a smoker If required, round your answers to three decimal places. For subtractive or negative numbers use a minus sign even if there is a + sign before the blank. (Example: -300) 2 + (b) Is smoking a significant factor in the risk of a stroke? Explain. Use a 0,05 level of significance. We - Select your answer - |reject the hypothesis that 83 = 0, Implying there - Select your answer - v sufficient evidence to conclude that smoking is a significant factor in the risk of a stroke. (c) what is the probability of a stroke over the next 10 years for Art Speen, a 67-year-old smoker who has a systolic blood pressure of 1727 If required, round your answer to two decimal places. Do not round intermediate calculations. What action might the physician recommend for this patient? The Input In the box below will not be graded, but may be reviewed and considered by your instructor.d) An insurance company will only sell its Select policy to people for whom the probability of a stroke in the next ten years is less than.01. If a smoker with a systolic blood pressure of 230 applies for a Select policy, under what condition will the company sell him the policy if it adheres to this standard? (1) The person must be at least 33 years old. (II) With this blood pressure measure, this person cannot qualify for a Select policy. (III) The person must be 33 years old or younger. (Iv) No smoker can qualify for a Select policy, - Select your answer - (e) What other factors could be included in the model as independent variables? Choose the correct answer below. (1) Family History of Stroke (il) Weight/obesity () Gender (iv) All of the above - Select your answer - v
