 * Kinds Of Pets Students Have**

__Problem 16. Write a paragraph about the pets these students have.__ Many people have fish, and I think that is because fish is the easiest to grow. It is simple, compared to other animals. You feed them by throwing food in their tank, and you don't have to clean it up if the don't eat it all. Sure, you do have to clean the tank, but that's way better than cleaning up litter. A lot of students also have a dog or a cat. On the other hand, there are few people that have a rabbit or a snake. Birds are the 4th most animals that students have. Horses and hamsters are in the middle. __Problem 17. What is a good estimation of how many people were surveyed? Why do you think that?__ A good estimate of how many students were surveyed is about 640 people, because for fish, the frequency is 303. Most students have at least 3 fish, so divide 303 and you get 101. Add all the frequency for the types of pets, and you get 639, rounded to 640.
