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, μ=100, σ=20.
The required value of X is,
z=Xμσ
0.50=X10020
X100=0.50×20=10
X=10010=90
The value of the random variable X if the Z-score equals –0.50 is 90.
