Answer 1

Question:

For a population with a mean of μ=45 and a standard deviation of σ=10. What is the corresponding z score if it has a score of X = 44?

Answer:

`z = -0.10`

Step-by-step explanation:

Given

`\mu = 45`

`\sigma = 10`

`x = 44`

Required

Calculate the z score

This is calculated as:

`z = (x - \mu)/(\sigma)`

So:

`z = (44 - 45)/(10)`

`z = (-1)/(10)`

`z = -0.10`
