The Coefficient of variation is 20%
We know that coefficient of variation (CV) is computed as :
CV = (SD / Mean) * 100
But
Standard deviation (SD)
= [tex]\sqrt240 / 15[/tex]
= [tex]\sqrt16[/tex]
= 4
Mean = 20
Hence,
CV = (4 / 20) * 100
CV = 0.2 * 100
CV = 20
Therefore, Coefficient of variation is 20%
