The sum and the s

Answer :

To find the more variable, we again need to compare the coefficients of variation (CV).


Here the number of products are n = 50 for length and weight both.


For length,


Mean =


Variance =


=


=


=


So, standard deviation, SD =


Therefore, the coefficient of variation of length,


CVL =


For weight,


Mean =


Variance =


=


=


=


So, standard deviation, SD =


Therefore, the coefficient of variation of length,


CVW =


Now, CVW > CVL


Therefore, the weight is more variable than height.
