Dr. Julie Aardvark, a plastic surgeon, had just returned from a conference in which she learned of a new surgical procedure for removing wrinkles around eyes, reducing the time to perform the normal procedure by 50 percent. Given her patient-load pressures, Dr. Aardvark is excited to try out the new technique. By decreasing the time spent on eye treatments or procedures, she can increase her total revenues by performing more services within a work period. Unfortunately, in order to implement...

A new weight-reducing technique, consisting of a liquid protein diet, is currently undergoing tests by the Food and Drug Administration (FDA) before its introduction into the market. A typical test performed by the FDA is the following: The weights of a random sample of five people are recorded before they are introduced to the liquid protein diet. The five individuals are then instructed to follow the liquid protein diet for 3 weeks. At the end of this period, their weights...
