Family A and Family B both have $8$ people in their family. The ages of each member is listed below.

Q$\mathrm{.}4)$ Which statement is correct about the variability of the two familes. Family A: $35,5,42,9,16,3,8,12$ Family B: $1,5,29,3,7,35,6,9$

A$.$ The variability is the same for both Family A and Family B because they have the same mean

absolute deviation.

B$.$ The variability for Family $A$ is greater because the mean is greater for Family $A.$

C$.$ The variability for Family B is greater because the mean absolute deviation is greater for Family B$.$

D$.$ There is not enough information to determine the variability.
