# Find the z-score for the value 52, when the mean is 58 and the standard deviation is 9.Group of answer choicesz=-0.78z=-0.74z=0.74z=-0.67

## Question

## Solution 1

The z-score is calculated using the formula:

z = (X - μ) / σ

where: X is the value we are interested in (in this case, 52), μ is the mean (in this case, 58), and σ is the standard deviation (in this case, 9).

Substituting these values into the formula, we get:

z = (52 - 58) / 9 z = -6 / 9 z = -0 Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
