The amount of beverage in a 16-oz bottle is normally distributed with a mean of16.2 oz and a standard deviation of 0.1 oz. Find the probability that the amount ofbeverage in a randomly select can is (a) between 15.5 and 16.2 oz, (b) more than16.4 oz, (c) less than 16.1 oz. NOTE: Please explain each part, so the problem can be used as a Study Guide
