(a) Using the event hall's service guideline, what is the probability of a stock-out associated with each replenishment decision? (Round your answer to four decimal places.)
(b) What is the replenishment level if demand during the review period plus lead-time period is normally distributed with a mean of 50 units and a standard deviation of 12 units? (Round your answer to the nearest integer.)
(c) What is the replenishment level if demand during the review period plus lead-time period is uniformly distributed between 45 and 95 units? (Round your answer to the nearest integer.)
