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. Suppose an
American man is randomly chosen. Let X = the amount of sodium
consumed. Round all numeric answers to 4 decimal places where
possible.
b. Find the probability that this American man consumes between 11
and 12.4 grams of sodium per day.
c. The middle 20% of American men consume between what two weights
of sodium? Round to whole numbers.

A certain factory consumes on average 1000 litres of water per
day with a variance (σ2) of 625 litres2. A random sample of 100
days taken revealed a mean daily consumption of x ̅ = 1006 litres.
At α = 0.01, test if the mean daily water intake remains 1000
litres against the alternative that the mean water consumption has
changed. please provide clear explaination

The average daily protein consumption of children in school is
30 grams. It is also known that its variance is 64 grams. Under the
Normal distribution assumption;
a) since these children are advised not to take less than 18
grams of protein, what is the proportion of children who receive
insufficient protein?
b) since it is known that 20% of children receive more protein
than recommended, what is the limit for excess protein?
