Making Selection Decisions

Marvin Albert is the new police chief for Holyfield, Georgia. As part of his plan to "take a bite out of crime," all police applicants will be administered the Comprehensive Personality Inventory (COPS). The test has good reliability (.90) and taps an individual's level of conscientiousness. If possible, the chief would like to increase the number of Hispanic officers on the force. According to the test manual, the COPS has a mean score of 85.6, a standard deviation of 7.30, and a suggested passing score of 80. Chief Albert needs to hire four new officers.
