The process time, denoted by p, is the time it takes to process a job, on average. The coefficient of variation in process times, denoted by CVp, is the standard deviation in process times, denoted by sp, divided by the mean process time, denoted by p. In the video showing how queues occur, what is the coefficient of variation in the process time? Hint: there are 12 jobs processed in the video, so there are 12 process times, each of which is 4 seconds (simulating 4 minutes). Find the mean and standard deviation of a set of 12 numbers, each of which is 4. Then take the standard deviation of that set of 12 numbers, and divide by the mean
