The average American man consumes 10 grams of sodium each day. Suppose that the sodium consumption of American men is normally distributed with a standard deviation of 8 grams. Suppose an American man is randomly chosen. Let X = the amount of sodium consumed. Round all numeric answers to 4 decimal places where possible.

b. Find the probability that this American man consumes between 11 and 12.4 grams of sodium per day.

c. The middle 20% of American men consume between what two weights of sodium? Round to whole numbers.
