They are curious to know if they should recommend regular exercise, appetite suppressants, or both to their patients. Suppose that a controlled experiment were conducted yielding the following results (see Figure 9.3). We will consider the proportion of those who lose at least 10 lbs. in a four-week period of time to be a success.
