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 57.4 milligrams. Assume the population is normally distributed and the population standard deviation is 6.9 milligrams. At a=0.04, can you reject the company's claim? Complete parts (a) through (e). CEZZET (a) Identify Ho and H₂. Choose the correct answer below. OA. Ho: 257.4 H₂: μ<574 OB. Ho: H=57.4 H₂:μ*57.4 C. Ho:p=55 H₂:55 OD. Ho: 255 H₂: <55 OE. Ho: #57.4 Ημ = 57,4 OF. Ho: *55 H₂: H=55 (b) Find the critical value(s). Select the correct choice below and fill in the answer box within your choice. (Round to two decimal places as needed.) A.
