3.103 Marketing a dietary supplement.

Your company produces a dietary supplement that contains a significant amount of calcium as one of its ingredients. The company would like to be able to market this fact successfully to one of the target groups for the supplement: men with high blood pressure.

You have available 30 men with high blood pressure who are willing to serve as subjects.
