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:

$z = -0.10$

Explanation:

Given

$\mu = 45$

$\sigma = 10$

$x = 44$

Required

Calculate the z score

This is calculated as:

$z = \frac{x - \mu}{\sigma}$

So:

$z = \frac{44 - 45}{10}$

$z = \frac{-1}{10}$

$z = -0.10$
