Reconsider the Sam’s Club store in the previous question. Assume that the supply lead time from HP is normal distributed with a mean of 2 weeks and a standard deviation of 1.5 weeks. How much safety inventory should Sam’s Club carry if it wants to provide a CSL of 95 percent? How does the required safety inventory change as the standard deviation of lead time is reduced from 1.5 weeks to zero in intervals of 0.5 weeks?
