Use a 0.05 level of significance.WeSelect your answer - V reject the hypothesis that B3 = 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 69-year-old smoker who has a systolic blood pressure of 172?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.blank(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.

Choose the correct answer below.(i) Family History of Stroke(ii) Weight/obesity(iii) Gender(iv) All of the above- Select your answer - V 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 isinterpreted 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 0 indicating a nonsmoker.SystolicRiskAgeBloodSmokerPressure1058152Yes2565163No1258155No5786177Yes2859196Yes5076189Yes1756155Yes3278120No3780135No157898No2271152No3670173Yes1567135Yes4877209Yes1560199No3682119Yes866166No3480125No462117No3859209Yes(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 x3 represent whether the person is a smoker.If required, round your answers to three decimal places.
