Obtain the value of the random variable X if the Z-score equals 0.75.
The value of the random variable X if the Z-score equals 0.75 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
0.75=X10020
X100=0.75×20=15
X=100+15=115
The value of the random variable X if the Z-score equals 0.75 is 115.
