Given the long wait time $($longer than one hour$)$ for Precinct A$,$ the city of Philadelphia is thinking of alternative solutions to improve voting conditions. One of the proposed solutions is as follows.

Proposal $1$: Deploy an additional voting machine in precinct A$.$

Assume that the voter turnout is expected to have similar characteristics in $2008$ as in the previous election.

Under Proposal $1,$ how long on average would a voter have to wait in line in precinct A in $2008$ before casting her$/$his vote. Circle the closest answer.

Blocking the bottleneck will increase the coefficient of variation of the arrival process, which decreases capacity.

Blocking the bottleneck increases inventory turns, which increases the annual holding costs.

It is not good to block the bottleneck because there are economies of scale in inventory management.

If the bottleneck is prevented from working $($e$.$g$.,$ it has nowhere to put its output$),$ the overall capacity will be reduced.
