Multiple Choice

Find the coefficient of variation for each of the two sets of data, then compare the variation. Round results to one decimal
place.
-Compare the variation in heights to the variation in weights of thirteen-year old girls. The heights (in inches) and weights (in pounds) of nine randomly selected thirteen-year old girls are listed below. $\begin{array} { l l l l l l l l l l } \text { Heights (inches) : } & 58.7 & 61.4 & 62.1 & 64.7 & 60.1 & 58.3 & 64.6 & 63.7 & 66.1 \end{array}$

A) Heights: $4.1 \%$
Weights: $15.2 \%$
There is substantially more variation in the weights than in the heights of the girls.
B) Heights: $11.8 \%$
Weights: $6.3 \%$
There is substantially more variation in the heights than in the weights of the girls.
C) Heights: 4.3\%
Weights: $16.0 \%$
There is substantially more variation in the weights than in the heights of the girls.
D) Heights: $4.5 \%$
Weights: $16.8 \%$
There is substantially more variation in the weights than in the heights of the girls.
