Dunstreet's department store would like to develop an inventory ordering policy of a 95% probability of not stocking out. To illustrate your recommended procedure, use as an example the ordering policy for white percale sheets. Demand for white percale sheets is 5000 per year. The store is open 365 days per year. Every two weeks (14 days) inventory is counted and a new order is placed. It takes 10 days for the sheets to be delivered. Standard deviation of demand for the sheets is five per day. There are currently 150 sheets on hand. From the Standard normal distribution, which z value should be used in the calculation of the quantity of sheets to be ordered? (Round to two decimal places) How many sheets should you order?
