1. Using the data assembled by Mr. McCarthy, compute revised cost figures for the two patients. What assumptions if any did you need to make?

2. How valuable are the cost figures you computed? That is, how might Dr. Leddy use them for decision making? Be as specific as you can identifying the kinds of decisions she might make with this new information-decisions related to pricing, profitability analysis, product cross subsidization, product elimination, physician behavior, and so on.

3. How might you improve on the data Mr. McCarthy has gathered? That is, if you had the opportunity, what additional data would you gather, and with what goals in mind?
