Problem$4.$ The following flowchart shows the main activities for processing on$-$line car insurance applications at an insurance company. Historical data indicate that all applications can be processed only one more time if any rework is necessary. Each activity's processing time and waiting time are listed in the table below. Please answer the following questions.

$\backslash$table$[[$Activity$,$Waiting Time $($min$),$Processing Time$($min$)],[$A$,7,3],[$B$,5,8],[$C$,4,2],[$D$,10,5],[$E$,7,2],[$F$,0,3],[$G$,2,5],[$H$,8,9],[$I$,2,8]]$

$($a$)$ What is the total processing time $($or theoretical cycle time$)$ of this process?

$($b$)$ What is the actual cycle time of this process?

$($c$)$ What is the cycle time efficiency?
