A company that makes cola drinks states that the mean caffeine content per 12-ounce bottle of cola is 45 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 46.4 milligrams. Assume the population is normally distributed and the population standard deviation is 6.2 milligrams. At a = 0.05, can you reject the company's claim? Complete parts (a) through (e). (a) Identify Ho and Ha. Choose the correct answer below. O A. Ho: H#45 O B. Ho: H#46.4 Hai µ= 46.4 O D. Ho: µ2 46.4 Ha:µ<46.4 Ha: µ= 45 O C. Ho: H= 46.4 HaiH#46.4 VE. Ho:µ=45 Ha: H#45 OF.
