question 9

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. $\begin{array} { l l l l l l l l l l } \text { Heights (inches) : } & 59.3 & 61.2 & 62.6 & 64.7 & 60.1 & 58.3 & 64.6 & 63.7 & 66.1 \\\text { Weights (pounds) : } &86 & 97 & 93 & 119 & 96 & 90 & 123 & 98 & 139 \end{array}$

• A)Heights: 4.3% Weights: 17.2%
• There is substantially more variation in the weights than in the heights of the girls.
• B)Heights: 4.1% Weights: 16.4%
• There is substantially more variation in the weights than in the heights of the girls.
• C)Heights: 3.9% Weights: 15.4%
• There is substantially more variation in the weights than in the heights of the girls.
• D)Heights: 11.5% Weights: 6.5%
• There is substantially more variation in the heights than in the weights of the girls.
