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, youfind 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 thepopulation standard deviation is 6.8 milligrams. At a = 0.08, 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: us53.9O B. Ho: u= 53.9Ha: H> 53.9Hai H#53.9O C. Ho: u#55Ha: = 55Ο D . Ho :μ= 5Ha: H#55Ο Ε. Hρ: μ5 55O F. Ho: H#53.9Ha: H= 53.9Ha: u> 55
