1855 program claims that program participants have a mean weight loss of at least 11 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 = 0.03, do you have enough evidence to reject the program's claim?
