$]$Consider a continuous review inventory system. Demand is normally distributed with an

average of $28,000$ per month and a monthly standard deviation of $4900$ units. Lead time

is $2$ weeks $($assume four weeks per month$)($round Z$-$values, standard deviations to two

decimal places$).$

If the firm desires $a(n)85\%$ cycle service level, it should hold units of safety

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