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?
(1 point)
• Cats, because the range of their weights is less than that of small dogs.
• Cats, because the range of their weights is greater than that of small dogs.
• Small dogs, because the range of their weights is greater than that of cats.
• Small dogs, because the range of their weights is less than that of cats.

Small dogs, because the range of their weights is less than that of cats. This can be observed by comparing the spread of the dots in the dot plots - the weights of small dogs are more concentrated around a central value, indicating less variability in their weights compared to cats.
