Jobs need processing at machine A$.$ Machine A has a mean time to failure of $5$ hours and a mean time to repair of $30$ minutes. The standard deviation of time to repair is $1$ hour. The average natural processing time is $5$ minutes with a standard deviation of $1$ minute. What is the squared coefficient of variation $($SCV$)$ of the effective process time, $c_e^2?$

Question $4$

Consider the situation in the previous question. When we double the mean time to failure, the mean time to repair, and the standard deviation of time to repair, the coefficient of variation will decrease.

True

False
