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. Piease round your answers to three decimal places. Enter negative value as negative number. Risk=-91.76(+ 1.077 Age + 0.252 Pressure + Smoker b. Is smoking a significant factor in the risk ofa stroke? Explain. Use a = 0.05. Compute the t test statistic for the significance of smoking (to 2 decimals). Use t table. 0.01 The p-value is between 0.01 and 0.025 What is your conclusion? Smoking is significant factor. C. What is the probability of a stroke over the next 10 years for Art Speen, a 68-year-old smoker who has blood pressure of 175? (to 2 decimals). Which of the following factors will the doctor recommend Art work on? Assume that by corresponds to the person's age, by to blood pressure, by to whether the person is a smoker. b2 and ba

Q1
Transcribed Image Text: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.
Please round your answers to three decimal places. Enter negative value as negative number.
Risk =-91.76+
1.077 Age +
0.252 Pressure +
Smoker
b. Is smoking a significant factor in the risk of a stroke? Explain. Use a = 0.05.
Compute the t test statistic for the significance of smoking (to 2 decimals). Use t table.
0.01
The p-value is between 0.01 and 0.025
What is your conclusion?
Smoking is
significant factor.
C. What is the probability of a stroke over the next 10 years for Art Speen, a 68-year-old smoker who has blood pressure of 175?
(to 2 decimals).
Which of the following factors will the doctor recommend Art work on? Assume that by corresponds to the person's age, by to blood
pressure, bs to whether the person is a smoker.
b2 and b3
Transcribed Image Text: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 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.
