Obtain the Z-score for the random variable X value equals 5.0.
The Z-score for the random variable X value equals 5.0 is obtained below as follows:
The required value is,
$Z=\frac{X-\mu }{\sigma }$
$=\frac{5.0-6.8}{2.5}$
$=\frac{-1.8}{2.5}=-0.72$
The Z-score for the random variable X value equals 5.0 is –0.72.
