  1. 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.. Let X = the amount of sodium consumed. Round all numeric answers to 4 decimal places where possible.

    What is the distribution of X? X ~ N(,)

    b. Find the probability that a randomly selected American man is select and he consumes less than 11 grams of sodium per day.
  2. Find the probability that a randomly selected American man consumes more than 12.4 grams of sodium per day.
  3. Find the probability that a randomly selected American man consumes between 11 and 12.4 grams of sodium per day.
