A company that makes cola drinks states that the mean caffeine content per 12-ounce bottle of cola is 35 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 33.4 milligrams. Assume the population is normally distributed and the
population standard deviation is 6.4 milligrams. At a= 0.01, 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= 35
O B. Ho: µs 35
H: µ> 35
Ha u#35
O C. Ho: µs33.4
Ha µ>33.4
O D. Ho: µ#35
H: µ= 35
O E. Ho: µ± 33.4
O F. Ho: H= 33.4
Ha: p= 33.4
Ha H#33.4
(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.)
O A. The critical value is
