A service manager is considering implementing a new technology which would reduce the$$variability$$of service times by $10\%,$ but would have no impact on their$$average$.$ Nor would it have any impact on arrival rates, the number of servers in operation or queue capacity. And, like the current system, there would be no blocking or abandonment due to excessive waiting times.

With the new technology, the average time a client spends in line would $\_\_\_\_($i$)\_\_\_\_$ and the average utilization of servers would $\_\_\_\_($ii$)\_\_\_\_$
