Question

Suppose the ages of cars driven by employees at a company are normally distributed with a mean of 8 years and a standard deviation of 3.2 years. What is the z score of a car that is 6 years old?

Answer 1

-0.625 is right

Explanation:

:3 i did the test

Answer 2

Z-scores are found using the formula
`z=(x-\mu) /\sigma`, where x is your data point you're using, μ is the mean, and σ is the standard deviation. Using our information we then have

`z=(6-8)/ 3.2=(-2)/ 3.2=-0.625`
