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
