*see attachment below for the dot plots

Answer:

A. The number of snacks grabbed for Class A has less variability than the number of snacks grabbed for Class B.

Explanation:

The extent of variability of the data represented on a dot plot can be determined by the range value.

Range is the difference between maximum value of the data set and the minimum value of the data set.

The larger the range, the more the data has more variability, while the smaller the range, the less the variability of the data.

Range for Class A = 37 - 15 = 22

Range for Class B = 45 - 12 = 33

Therefore, class B has more variability in the number of snacks grabbed compared to Class A.

Correct statement is: "The number of snacks grabbed for Class A has less variability than the number of snacks grabbed for Class B."
