Question:
A Credit Union has a small branch in which a single customer service representative serves the needs of customers who arrive at an average rate of 24 per hour. The service representative can typically handle 30 customers per hour. Based on an analysis of historical data, it is reasonable to assume that customer interarrival times and service times are exponentially distributed. Assume that all arriving customers enter the branch, regardless of the number already waiting in line.
What percentage of all customers have to spend at least some small amount of time waiting in line?
30% | ||
54% | ||
80% | ||
90% | ||
None of the above |
