The average American man consumes 9.9 grams of sodium each day. Suppose that the sodium
consumption of American men is normally distributed with a standard deviation of 1 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.
