A study reports that about half of pet owners have either a dog or a cat. The other half of pet owners have birds, reptiles, or other animals. To find out if this applies in its area, an animal shelter surveys a random sample of 30 pet
owners. Nineteen of them say they own either a cat or a dog.
Let even digits represent owning a cat or a dog and odd digits represent owning some other type of animal.
