Answer:
Decrease the average waiting time
Explanation:
A single-channel queuing system has an average service time of 16 minutes per customer, which is exponentially distributed. The manager is thinking of converting to a system with a constant service time of 16 minutes. The arrival rate will remain the same. The effect will be to DECREASE THE AVERAGE WAITING TIME that is reducing variability will reduce waiting time.
