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 4ml.

the probability that a randomly selected bottle will have less than 325ml of beer is .10565

What middle interval captures the fill of 95% of all bottles?

.0011 of the 6 pack of beer bottles have a mean amount less than 325

What middle interval captures the mean fill of 95% of all 6 packs?
