Question 6 2 pts Gap Company has 177 retail stores across the U.S.. Daily demand for jeans at each Gap store is identically distributed following normal distribution with a mean of 198 and a standard deviation of 34. Each Gap store monitors its inventory continuously and place orders independently. There are uncertainties for supply factories to fulfill and ship a Gap order. Specifically, the lead time varies and it generally follows a normal distribution with a mean 11 days and a standard deviation of 3 days. Gap is targeting a service level of 98% (use Z=normsinv(98%)=2.05 in your calculation). How much safety stock of jeans should Gap Company carry in its retail stores overall in order to provide its customers the targeted service level? Input numbers only, keep 3-decimal if not exact, either round up or down is ok
