Answer: We can expect about 40.13% of bottles to have a volume less than 32 oz.
Explanation:
Given : The volumes of soda in quart soda bottles can be described by a Normal model with

Let X be the random variable that represents the volume of a randomly selected bottle.
z-score :

For x = 32 oz

The probability of bottles have a volume less than 32 oz is given by :-
[Using standard normal table]
In percent,

Hence, we can expect about 40.13% of bottles to have a volume less than 32 oz.
