Statewide Auto Parts uses a four-week periodic review system to reorder parts for its inventory stock. A one-week lead time is required to fill the order. Demand for one particular part during the five-week replenishment period is normally distributed with a mean of 20 units and a standard deviation of 8 units. Do not round intermediate calculations. At a particular periodic review, 7 units are in inventory. The parts manager places an order for 20 units. What is the probability...
