Beer bottles are filled so that they contain an average of 330 ml of beer in each bottle. Suppose that the amount of beer in a bottle is normally distributed with a standard deviation of 8 ml.[You may find it useful to reference thez table.]

a.What is the probability that a randomly selected bottle will have less than 328 ml of beer?(Round intermediate calculations to at least 4 decimal places, "z" value to 2 decimal places, and final answer to 4 decimal places.)

b.What is the probability that a randomly selected 6-pack of beer will have a mean amount less than 328 ml?(Round intermediate calculations to at least 4 decimal places, "z" value to 2 decimal places, and final answer to 4 decimal places.)

c.What is the probability that a randomly selected 12-pack of beer will have a mean amount less than 328 ml?(Round intermediate calculations to at least 4 decimal places, "z" value to 2 decimal places, and final answer to 4 decimal places.)
