Parts arrive at an automated machining center at a rate of 89 per hour, based on a Poisson distribution. The machining center is able to process these parts at a fixed rate of 100 per hour. That is, each part will take exactly 60/100=0.6 minutes to process a. The average number of parts waiting to be processed is (Enter your response rounded to two decimal places.) The average number of parts in the system (i.e., waiting and being processed) is 4.49. (Enter your response rounded to two decimal places.) b. A part will have to wait 2.4 minutes, on average, before it is processed. (Enter your response rounded to one decimal place.)
