The historian of a town with about 1900 households conducts a study to determine the average number of years each family has lived in the town. He randomly selects 1012 addresses from property records and observes a mean of 21.2 years and a standard deviation of 5.1 years of residency for those households. A histogram of the data shows a roughly symmetric curve with one peak.
