Reconsider the expose machine of Problem $3$ with mean time to expose a single panel of $2$ minutes with a standard deviation of $1\frac{1}{2}$ minutes and jobs of $60$ panels. As before, failures occur after about $60$ hours of run time, but now happen only between jobs $($i$.$e$.,$ these failures do not preempt the job$).$ Repair times are the same as before. Compute the effective mean and $CV$ of the process times for the $60-$panel jobs. How do these compare with the results in Problem $3?$

Consider two different machines A and B that could be used at a station. Machine A has a
