cycletime for the whole drive$-$thru process $($this is defined in Exercise $4),$ the service levels both inside and outside, and the fraction time working of Pay$/$Pickup$.$

b$.$ Run $100$ simulations of the model with the cross$-$trained worker. Report the same numbers as in part a$.$ Also report the "mean number in use" for the resource CT Worker $($this can be found at the bottom of the Results page$).$ This represents the fraction of time the cross$-$trained worker is working and should be equal to the sum of the fraction time working of Pay$/$Pickup and Cashier $3.$
