A research company desires to know the mean consumption of milk per week among males over age 45. They believe that the milk consumption has a mean of 4.5 liters, and want to construct a 95% confidence interval with a maximum error of 0.08 liters. Assuming a variance of 1 liters, what is the minimum number of males over age 45 they must include in their sample? Round your answer up to the next integer.

level, that is the subtraction of 1 by the confidence interval divided by 2. So:
.
, so 
is the standard deviation of the population(square root of the variance) and n is the size of the sample.
