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.
