A normal distribution $\mu =30$ and $\sigma =5$
Find the z score corresponding to $x=25$.

Usamah Prosser

$\mu =30$, $\sigma =5$, $x=25$.
We use the formula for normal distribution:
$z=\frac{x-\mu }{\sigma }$
$z=\frac{25-30}{5}$
$z=-1.0$
The z score corresponding to $x=25$ for normal distribution with $\mu =30$, $\sigma =5$ is -1.0.
