B. Small dogs, because the range of their weights is less than that of cats
In this case, the range of the weights of small dogs is smaller than the range of the weights of cats, indicating that there is less variability in the weights of small dogs compared to cats.
Weight cats 9=1. Weight small dogs 8=1
10=2. 9=2
11=4. 10=4
12=2. 11=2
13=1. 12=2
13=2
14=1
15=1
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 less than that of cats
C. Small dogs because the range of their weights is greater than that of cats
D. Cats because the range of their weights is less than of small dogs
