The average American man consumes 9.5 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. a. What is the distribution of X? X ~ N( b. Find the probability that this American man consumes between 9.7 and 10.5 grams of sodium per day. c. The middle 20% of American men consume between what two weights of sodium? Low: High:
