A researcher uses a matched-subjects design to investigate whether single people with pets are happier than singles without pets. A mood inventory survey is given to a group of 20 to 29-year-old non-pet owners and a similar aged group of pet owners. The pet owners are matched one to one with the non-pet owners for income, number of close friendships, and general health. Are pet owners significantly happier than non-pet owners?
