The producer of a weight-loss pill advertises that people who use the pill lose, after one week, an average (mean) of 1.8 pounds with a standard deviation of 1.05 pounds. In a recent study, a group of 60 people who used this pill were interviewed. The study revealed that these people lost a mean of 1.83 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 60 individuals will be 1.83 pounds or less? Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.

5. A weight loss program advertises that participants in this program lose, on the average, 15 pounds. A random sample of 19 participants yielded a sample mean (X) of 14.73, and a sample standard deviation (%) of 2.2. Is this sufficient statistical evidence that would make us not believe the claim offered by the program? Clearly state the null and alternate hypotheses, along with any signiicant statıstical evidence used to reach your decision.
