On a recent quiz, the class mean was 69 with a standard deviation of 4.8. Calculate the z score for a person who received score of 74. z score:

1.04167

Step-by-step explanation:

Z -score formula is given as

z = (x-μ)/σ, where

x is the raw score = 74

μ is the population mean = 69

σ is the population standard deviation = 4.8

Z score = x - μ/ σ

= 74 - 69/4.8

= 1.04167

The z score for a person is given as 1.04167
