please answer question thanks!

A Cake company uses 4,928 quart bottles of Chocolate sauce each year. The sauce costs 5 per bottle and is served only in full bottles for food safety purposes. The company's inventory manager calculated that each time an order is placed it costs 18 and holding costs are 19 percent of the purchase price. Once the order is placed, it takes 4 weeks for an order to arrive. The company works for 49 weeks per year. The company is considering to use the inventory system techniques which minimizes the inventory cost. Suppose that things have become uncertain and that customer demand is no more constant. Customer demand is now normally distributed with mean being the same as given in the problem description and standard deviation :) - 36units per week. The supply source is still very reliable and as a result the lead time is almost constant. Find out the safety stock needed to achieve 95% customer service level. (use the z table (normal distribution table) given on the study guides or in the textbook). Consider Std. Dev of lead time as O for uncertainty
