Question

The head of a city’s Recreation Department feels that the employees of the ­department are the best in the city. Each year, all city employees receive a standardized performance evaluation that rates them on a scale of performance: “far above expectations,” “above expectations,” “meets expectations,” “below expectations,” and “far below expectations.” (Each rating has an operational definition.) The department head feels that his assessment of employees will be justified if at least 90% of them fall into the top two categories. The ratings received by department employees are shown in the accompanying table.

Far above expectations ……………………. 15
Above expectations ……………………. 22
Meets expectations ……………………. 77
Below expectations ……………………. 9
Far below expectations ……………………. 8
