Consider a continuous review inventory system. Demand is normally

distributed with an average of $2000$ per month and a monthly standard

deviation of $400$ units. Lead time is $8$ weeks $($assume four weeks per month$).$

Please round Z$-$values and standard deviations to two decimal places.

If the firm desires a$($n$)88\mathrm{.}30\%$ cycle service level, it should hold

units of

safety stock $($round your response to the nearest integer$).$
