The systolic and diastolic blood pressure (mm Hg) was recorded for 30 patients with moderate essential hypertension (Table below) [1]. Half of the group was measured immediately after taking the drug captopril (Drug=2) while the other half received a placebo (Drug=l). The dataset bld.dat is (a) Fit a single regression model to predict Diastolic from Systolic BP, with separate slopes and intercepts for each Drug. (b) Determine if the slopes are different for each Drug. (c) Determine if the intercepts are different for each Drug.

Explanation / Answer

For Drug 1,

Diastolic= 51.39182 + 0.379922*Systolic

From Drug 2,

Diastolic = 56.50779 + 0.317556* Systolic

(b) Slopes for each drug are different .

(c) Intercepts are different for each drug.
