Beer bottles are filled so that they contain an average of 335 ml of beer in each bottle. suppose that the amount of beer in a bottle is normally distributed with a standard deviation of 7 ml. [you may find it useful to reference the z table.] a. what is the probability that a randomly selected bottle will have less than 332 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 332 ml? (round intermediate calculations to at least 4 decimal places, “z” value to 2 decimal places, and final answer to 4 decimal places.)
