Dr. Bark is interested in the different ways that people interact with their pets, specifically how long people talk to their pets, comparing dog and cat owners. She randomly selected two samples of pet owners from a pool of volunteers, 12 people that own dogs and 15 people that own cats. Each human/pet pair was placed one at a time in a lab room. Each pair was observed for ten minutes and the total amount of time that the person spent talking to their pet was recorded. (Remember that a person might not have talked to their pet at all.) The data is presented below.
