<h3>What is a z-score?</h3>

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The z-score is given as

z = \dfrac{x-\mu }{s}\\

x = 29

s = 3.6

z = 1.5

Then the mean will be

1.5 = \dfrac{29 - \mu }{3.6}\\\\\mu = 29 - 5.4\\\\\mu = 23.6 \approx 24

More about the z-score link is given below.
