A cоmpаny thаt mаkes cоla drinks states that mean caffeine cоntent in a 12-ounce bottle of cola is 40 milligrams. You want to test whether their claim is correct. For the test, you find that a random sample of 28 bottles of cola has a mean caffeine content of 39.2 milligrams and a standard deviation of 7.5 milligrams. The null and alternative hypotheses you use to test this would be:
