Answer 2

Answer:

The Coefficient of Variation is 0.2

Step-by-step explanation:

• Coefficient Of Variation: It is a statistical measure of the relative dispersion of data  in a data series around the mean.
• It is the ratio of the standard deviation and the mean
• It is given by  

          $COV=\frac{\sigma}{\ mean}$

         where $\sigma$ is the standard deviation

Step 1 of 1:

• Given mean = 75
• Standard deviation=15
• Coefficient of Variation given by  

          $COV=\frac{\sigma}{\ mean}$            

       $COV=\frac{15}{75}$

        COV=0.2

Conclusion:

The Coefficient of Variation is 0.2
