The dot plots show the weights of randomly selected cats and small dogs in different households. Based on an informal assessment of the visual overlap of these distributions which animal has the least variability in their weights? Why?
A. Cats, because the range of their weights is greater than that of small dogs
B. Small dogs because the range of their weights is greater than that of cats
C. Cats because the range of their weights is less than that of small dogs
D. Small dogs because the range of their weights is less than that of cats

C. Cats because the range of their weights is less than that of small dogs

Looking at the dot plots, it appears that the weights of cats are clustered closely together with less variability than the weights of small dogs which are more spread out. This is further supported by the fact that the range of the weights of the cats (3 pounds) is smaller than the range of weights of the small dogs (3 pounds).
