Solve the Problem $$\text { coefficient of variation } = 100 ( \mathrm {~s} / \overline { \mathrm { x } } )$$

Solve the problem.
-The coefficient of variation, expressed as a percent, is used to describe the standard deviation relative to the mean. It allows us to compare variability of data sets with different measurement units and is calculated as follows: $$\text { coefficient of variation } = 100 ( \mathrm {~s} / \overline { \mathrm { x } } )$$
Find the coefficient of variation for the following sample of weights (in pounds) :
$\begin{array} { l l l l l } 139 & 136 & 186 & 105 & 197 \\ 133 & 172 & 152 & 116 & 125 \end{array}$

A) $22.7 \%$
B) $18.2 \%$
C) $25.4 \%$
D) $20.7 \%$
