12) Jordan creates a survey with 25 of her friends to determine what types of pets they have. The results of the survey can be seen below

Pet	Number
Dog	12
Cat	7
Goldfish	8
Hamster	3

Based on the data in table, we know that:

1. All of those interviewed have a pet.
2. Some of those interviewed have more than one pet.
3. A majority of the people interviewed have dogs.
4. The least favorite pet is Hamster.
5. Some of those interviewed did not have a pet.

The only thing we know for sure is that some of those interviewed have more than one pet. This can be determined by the fact that there are more pets then people interviewed. As such, at least one of those interviewed must have more than one pet.

The rest of the answers may or may not be true, but we don't have enough information to determine if they are correct.
