• Example 2: A group of physicians specializing in weight loss is interested in knowing whether appetite suppressants are effective in helping people lose weight. 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.
