A recent 10-year study conducted by a research team at the
Medical School was conducted to assess 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.
