1. Independent Measurest
Researchers have reported that elderly people who own pets are less likely to visit the doctor after upsetting events than those who do not own pets. A researcher compares a sample of elderly pet owners to a group that does not own pets but is otherwise matched for age and income. The data that are recorded (see below) are number ofvisits to the doctor in the course of a year. We would like to determine if these data support the previous findings.
