Obtain the value of the random variable X if the Z-score equals –0.50.
The value of the random variable X if the Z-score equals –0.50 is obtained below as follows:
Let X denotes the random variable with the population mean of 100 and standard deviation of 20.
That is, $\mu =100$, $\sigma =20$.
The required value of X is,
$z=\frac{X-\mu }{\sigma }$
$-0.50=\frac{X-100}{20}$
$X-100=-0.50×20=-10$
$X=100-10=90$
The value of the random variable X if the Z-score equals –0.50 is 90.
