The volumes of soda in quart soda bottles can be described by a normal model with a mean of 32.3 oz and a standard deviation of 1.2 oz. what percentage of bottles can we expect to have a volume less than 32 oz?

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

Step-by-step 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.
