QUESTION 3 Suppose that the demand during lead time follows a normal distribution N(20,20) and the order quantity is 100. In order to maintain a service level (Type II)= 90%, calculate the standardized loss function [E(Z) = ( 100-SL(11)Q/ 1000] 25% 50% 75% 100% QUESTION 3 Suppose that the demand during lead time follows a normal distribution N(20,20) and the order quantity is 100.
