Obtain the Z-score for the random variable X value equals 6.2.
The Z-score for the random variable X value equals 6.2 is obtained below as follows:
Let X denote the random variable with the population mean 6.8 and the standard deviation of 2.5.
The required value is,
Z=Xμσ
=6.26.82.5
=0.62.5=0.24
The Z-score for the random variable X value equals 6.2 is -0.24.
