1. What is the average number of residents in a complex with 50 units? 2. Management wants to make sure maintenance supply costs don't get out of hand-they should remain below $2500 per complex per month. Each month, they will examine the records from a small randomly chosen sample of several complexes.

What would you suggest as a criterion for determining when the more careful examination seems to be required? Suppose you have decided on a sample of size ten.
