1. A prison administrator is interested in examining the relationships between the type of prison security (maximum, medium, and minimum) and the number of previous offenses committed by an inmate. He believes that maximum security prisons have inmates with many prior offenses, medium security with not so many offenses, and minimum security with almost no prior offenses. He randomly selects eight new inmates from each of the three security levels and compares the number of offenses for which they have ever been charged.
