A company that makes cola drinks states that the mean caffeine content per 12-ounce bottle of cola is 40 milligrams. Yo 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 40.4 milligrams. Assume the population is normally distributed and the population standard deviation is 6.1 milligrams. At x = 0.01, can you reject the company's claim? Complete parts (a) through (e). (a) Identify Ho and H₂. Choose the correct answer below.

During your tests, you find that a random sample of thirty 12-ounce bottles of cola has a mean caffeine content of 40.4 milligrams. Assume the population is normally distributed and the population standard deviation is 6.1 milligrams. At α = 0.01, can you reject the company's claim? Complete parts (a) through (e). (a) Identify Ho and H₂. Choose the correct answer below. OA. Ho: μ240.4 Hg: μ < 40.4 O C. Ho: μ = 40 H₂:µ‡40 O E. Ho: μ#40.4 H₂:μ=40.4 O B. Ho: μ = 40.4 H₂:μ#40.4 a O D. Ho: μ#40 H₂:μ = 40 OF. Ho:μ ≥40 Ha: μ< 40
