Suppose that the demand during lead time is normally distributed with an average of 85 and dLT (standard deviation of the demand during the lead time) =40. Compute the safety stock for a 90 percent cycle-service level (round it to nearest integer). \begin{tabular}{l} 51 \\ 136 \\ 40 \\ \hline 36 \\ \hline 76 \end{tabular}
