A)4.47
B)24.00
C)5.26
D)0.19

Quizplus · Accepted Answer

The coefficient of variation is calculated as the standard deviation divided by the mean, then multiplied by 100 to express it as a percentage. So, $ \frac{24}{129} \times 100 = 18.6\% $. Since none of the options exactly match this result, the closest option, when considering the coefficient of variation as a decimal (which is not standard but may be implied), is $ \frac{24}{129} = 0.186 $, which rounds to 0.19, making D the correct choice.
