A recent 10-year study conducted by a research team at the Great Falls Medical School was conducted to assess haw age, systolic bioud 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 grobability (times 100) that the pabent will have a stroke over the next 10 -year period. For the smoking variable, define a dummy variable with 1 indicating a smoker and 0 indicating a nonsmoker. (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 x1 represent the person's age. Let x2 represent the person's systolic blood pressure. Let xy represent whether the person is a smoker. If required, round your answers to threg decimal places. For subtractive or negotive numbers use a minus sign even if there is a + sign before the blank. (Example; - 300) y= (b) Is smoking a wignificant factor in the risk of a stroke? Explain. Use a 0.05 level of significance. We reject the hypothesis that 3=0, implying there 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 66 -year-old smoker who has a systoic blood pressure of 176? If required, round your answer to two decimal places. Do not round intermediate calculations. What action might the physican recommend for this patient? The input in the box below will not be graded, but may be reviewed and considered by your instructor. If required, reund your answer to two decimal places: Do not round intermediote caiculations What action might the physician recomimend for this potient? The ingut in the box below will not be graded, but may be reviewed and considered by your instructor. (d) An insurance company will oaly sell its Select policy to people for whom the probability of a stroke in the next ten years is less than. D1. If a Mnoker with a systolic blood pressure of 230 applies for a Select policy, under what cons will the company sell him the policy if it adheres to this standard? (i) No moker can qualify for a Select policy. (ii) With this blood pressure meawure, this person cannot qualify foc a Select policy. (iii) The person must be ot least 33 years old. (iv) The person must be 33 years old or younger. (c) What other factors could be induded in the model as independent vanables? Choose the carrect answer below. (1) Family History of Stroke (ii) Weight/obesity (iii) Gender (iv) All of the above
