Waiting Time

$3$ points possible $($graded$)$

At a given utilization, does increasing variability increase or decrease the waiting time?

$$ Increase

$$ Decrease

If there is no variability in a system, if the resource utilization is less than $100\%,$ is there any queuing before the resource?

$$ Yes

$$ No

Based on the graph above, for low values of resource utilization, waiting is a severe problem, true or false?

$$ True

$$ False
