Obtain the Z-score for the random variable X value equals 7.2.
The Z-score for the random variable X value equals 7.2 is obtained below as follows:
Let X denote the random variable with the population mean 7.2 and the standard deviation of 2.5.
The required value is,
Z=Xμσ
=7.26.82.5
=0.42.5=0.16
The Z-score for the random variable X value equals 7.2 is 0.16.
