Now suppose the mean time to failure mf on the expose, Ask an Expert

Engineering

The mean time to expose a single panel in a circuit-board plant is 2 minutes with a standard deviation of 1.5 minutes.

(a) What is the natural coefficient of variation?
(b) If the times remain independent, what will be the mean and variance of a job of 60 panels? What will be the coefficient of variation of the job of 60?
(c) Now suppose the mean time to failure (mf) on the expose machine is 60 hours and the repair time is exponentially distributed with a mean of 2 hours (mr). What are the effective mean and CV of the process time for a job of 60 panels?
