The average American man consumes 9.5 grams of sodium each day.Suppose that the sodium consumption of American men is normallydistributed with a standard deviation of 0.8 grams. Suppose anAmerican man is randomly chosen. Let X = the amount of sodiumconsumed. Round all numeric answers to 4 decimal places wherepossible.
a. What is the distribution of X? X ~ N( , )
b. Find the probability that this American man consumes between8.6 and 9.5 grams of sodium per day.
c. The middle 20% of American men consume between what twoweights of sodium? Low: High:
