Read the treemap and
answer the questions.
Q4 Remember: The animals in the small animal group cannot fit any of the six other categories. For example, if you were thinking a duck is a small animal, that doesn’t fit the data. A duck is a bird so households with ducks would already be included in the 6 million count for birds. The data for small animals could include households with a rabbit, hamster, guinea pig, mouse, gerbil, toad, or salamander.
Q5 Hint: rereading the title may help you answer this question. Answer: B The treemap does not show data for the number of animals. It shows data for the number of households with each type of pet.
