Reconsider the expose machine of Problem 3 with mean time to expose a single panel of two minutes with a standard deviation of one and one-half 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.
