The producer of a weight-loss pill advertises that people who use the pill lose, after one week, an average (mean) of pounds with a standard deviation of pounds. In a recent study, a group of people who used this pill were interviewed. The study revealed that these people lost a mean of pounds after one week. If the producer's claim is correct, what is the probability that the mean weight loss after one week on this pill for a random sample of individuals will be pounds or more? Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
