A brewery's filling machine is adjusted to fill bottles with a mean of 34 oz. of ale and a variance of 0.007. Periodically, a bottle is checked and the amount of ale noted.

A brewery's filling machine is adjusted to fill bottles with a mean of 34 oz. of ale and a variance of 0.007. Periodically, a bottle is checked and the amount of ale noted.
(a) Assuming the amount of fill is normally distributed, what is the probability that the next randomly checked bottle contains more than 34.16 oz? (Give your answer correct to four decimal places.)
(b) Let's say you buy 102 bottles of this ale for a party. How many bottles would you expect to find containing 34.16 oz. of ale? (round to the nearest whole number)
