7. An internal auditor works for a car rental agency that operates a fleet of 75,000 vehicles in 1,000 cities throughout North America.

A computer program showed that 20% of the fleet has been in service for more than 12 months. A sample of 375 is drawn based on: Confidence level = 95% Expected rate of occurrence = 10% Precision = 3% If 30 of the vehicles tested had received major repairs after being in service for more than 12 months, which is the sample rate of occurrence?
