Question:
Important risk factors for high blood pressure reported by the National Institute of Health include weight and ethnicity. High blood pressure is common in adults who are overweight and are African-American. According to the American Heart Association, the systolic pressure (top number) should be below 120. In a recent study, a public policy researcher in Atlanta surveyed 150 adult men in the 55-60 age group. Data was collected on their systolic pressure, weight (in pounds), and race (Black = 1 for African-American; 0 otherwise); a portion of the data is shown in the following table.
a. Estimate and interpret the effect of Weight and Black on Systolic. Predict the systolic pressure of black and non-black adult men with a weight of 180 pounds.
b. Extend the model in part a to include the interaction between Weight and Black. Predict the systolic pressure of black and non-black adult men with a weight of 180 pounds.
