Question

- 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. - Find the probability that a randomly selected American man consumes more than 12.4 grams of sodium per day.
- Find the probability that a randomly selected American man consumes between 11 and 12.4 grams of sodium per day.
