A company that makes cola drinks states that the mean caffeine content per 12-ounce bottle of cola is 55 milligrams. You want to test this claim. During your tests, you find that a random sample of thirty 12-ounce bottles of cola has a mean caffeine content of 53.9 milligrams. Assume the population is normally distributed and the population standard deviation is 6.8 milligrams. At a = 0.08, can you reject the company's claim? Complete parts (a) through (e). ....
