A weight loss program claims that program participants have a mean weight loss of at least 12 pounds after 1 month. You work for a
medical association and are asked to test this claim. A random sample of 30 program participants and their weight losses (in pounds) after
1 month is listed in the table below. Assume the population standard deviation is 3. At a = 0.02, do you have enough evidence to reject the
program's claim? Complete parts (a) through (e).
