Possible Answers:

The Snake Exhibit is the least popular  

The Fish Exhibit is the least popular 

No inference can be made based on this data

The Panda Exhibit is the least popular 

Correct answer:

The Fish Exhibit is the least popular 

Explanation:

We can use data from a random sample to make inferences about a population. In this case, our population is all of the visitors of the zoo on Friday, and the random sample is the  visitors that were randomly selected by the owner and asked which exhibit was their favorite.

Based on our answer choices, we are making an inference about which animal exhibit is the least popular. The fish received the least votes out of the owner's pole; thus, we can infer—based on these results—that the Fish Exhibit is the lest popular exhibit at the zoo.
