b. Find the probability that this American man consumes between 9.3 and 11.2 grams of sodium per day. 

The average American man consumes 9.6 grams of sodium each day. Suppose that the sodium consumption
of American men is normally distributed with a standard deviation of 0.8 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? XN( 9.6
