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 0.9 grams. Suppose and American man is randomly chosen. Let X= the amount of sodium consumed. Round all numeric answers to 4 decimal places where possible.
1. What is the distribution of X? X~N ( , )
2. Find the probability that this American man consumes between 10.9 and 11.5 grams of sodium per day.
3. The middle 10% of American men consume betweeen what two weights of sodium? Low: High:
