Answer: 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
![\mu=\text{32.3 oz}\\\\\sigma=\text{1.2 oz}](https://tex.z-dn.net/?f=%5Cmu%3D%5Ctext%7B32.3%20oz%7D%5C%5C%5C%5C%5Csigma%3D%5Ctext%7B1.2%20oz%7D)
Let X be the random variable that represents the volume of a randomly selected bottle.
z-score :![\dfrac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
For x = 32 oz
![z=\dfrac{32-32.3}{1.2}=-0.25](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B32-32.3%7D%7B1.2%7D%3D-0.25)
The probability of bottles have a volume less than 32 oz is given by :-
[Using standard normal table]
In percent, ![0.4012937\times100=40.12937\%\approx40.13\%](https://tex.z-dn.net/?f=0.4012937%5Ctimes100%3D40.12937%5C%25%5Capprox40.13%5C%25)
Hence, we can expect about 40.13% of bottles to have a volume less than 32 oz.
