A hospital orders surgical supplies using a fixed order interval system. Suppose that just prior to ordering, a check of rolls of gauze bandages shows that there are 40 currently on hand. Suppose also that these rolls have a daily usage that is approximately normal with a mean of 9 rolls and a standard deviation of 4 rolls. Lead time is 4 days and the desired service level is 98 percent. The order interval is 12 days What's the expected demand during the order interval and lead time? * 2 points 33 rolls 53 rolls 137 rolls 144 rolls
