Assume that the data in the file emphysema.xlsx are from a portion of this study. Risk is interpreted as the probability (times 100) that the patient will develop emphysema 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 linear regression equation that relates risk of developing emphysema to the person's age, systolic blood pressure, and whether the person is a smoker. (Let x1 represent age, x2 represent blood pressure, x3 represent whether the person is a smoker, and y represent risk. Round your numerical values to four decimal places.) ŷ = (b) Is smoking a significant factor in the risk of developing emphysema? Explain. Use a ? = 0.05 level of significance. Find the p-value.

What action might the physician recommend for this patient? This answer has not been graded yet. (d) An insurance company will only sell its Select policy to people for whom the probability of developing emphysema in the next 10 years is less than 0.01. If a smoker with a systolic blood pressure of 175 applies for a Select policy, under what condition will the company sell the smoker the policy if it adheres to this standard?

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 emphysema. Assume that the data in the file emphysema.xlsx are from a portion of this study. Risk is interpreted as the probability (times 100) that the patient will develop emphysema 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 linear regression equation that relates risk of developing emphysema to the person's age, systolic blood pressure, and whether the person is a smoker. (Let x₁ represent age, x₂ represent blood pressure, x₃ represent whether the person is a smoker, and y represent risk. Round your numerical values to four decimal places.)

ŷ =

(b)

Is smoking a significant factor in the risk of developing emphysema? Explain. Use a ? = 0.05 level of significance.

Find the p-value. (Round your answer to four decimal places.)

p-value =

State your conclusion.

Reject H₀. There is sufficient evidence to conclude that smoking is a significant factor.Reject H₀. There is insufficient evidence to conclude that smoking is a significant factor. Do not reject H₀. There is insufficient evidence to conclude that smoking is a significant factor.Do not reject H₀. There is sufficient evidence to conclude that smoking is a significant factor.

(c)

What is the probability of developing emphysema over the next 10 years for Art Speen, a 67-year-old smoker who has a systolic blood pressure of 180? (Round your answer to four decimal places.)

What action might the physician recommend for this patient?

This answer has not been graded yet.

(d)

An insurance company will only sell its Select policy to people for whom the probability of developing emphysema in the next 10 years is less than 0.01. If a smoker with a systolic blood pressure of 175 applies for a Select policy, under what condition will the company sell the smoker the policy if it adheres to this standard? (Round your answer to the nearest integer.)

This person must be no more than years old to qualify for the Select policy.
