A drilling department Orion Manufacturing Inc. has five drill press machines and has one repair technician to service these machines. Each drill press operates for an average of 10 hours (negative exponentially distributed) before requiring maintenance work. It takes the service technician about two hours to repair a machine, and the repair times are found to follow a negative exponential distribution. Machine downtime costs the company $150 an hour, and the service technician is paid $35 an hour. Determine whether Orion Manufacturing needs a second repair technician.
