Stevens manufactures component parts for the Department of Defense (DOD). There are a number of "C" that are used for the product structure. The Skid Brace Tube (SBT) is one such component part. Daily demand for the SBT is 75 units with a standard deviation of 15 units. The review period is 30 days, and the lead time is 5 days. At the time of the review there are 96 units in stock. If 98 percent of all SBT demand is to be satisfied from items in stock, how many units should be stocked?
