If some one could solves these that would be great. This is an extra credit assignment and I need all of the help I can get in this class. Thanks in advance!

PA 14-5 (Algo) You are the owner of Hotspices.com, an online retailer... Use Table 14.1 You are the owner of Hotspices.com, an online retailer of hip, exotic, and hard-to-find spices. Consider your inventory of saffron, a spice (generally) worth more by weight than gold. You order saffron from an overseas supplier with a shipping lead time of three weeks and you order weekly. Average weekly demand is normally distributed with a mean of 44 ounces and a standard deviation of 32 ounces. Use Table 14.1. Round your calculated z value to the nearest 0.1 increment. Round your answer to the nearest integer. a. Suppose it uses an order-up-to level of 297 ounces. What is its expected on-hand inventory? Round your answer to the nearest integer. b. Suppose it uses an order-up-to level of 225 ounces. What is its expected on-order inventory? Use Table 14.1. Round your calculated z value to the nearest 0.1 increment. Round your answer to 4 decimal places. c. Suppose it uses an order-up-to level of 378 ounces. What is its in-stock probability? Use Table 14.1. Choose the z value with a cumulative probability AT LEAST as high as the required in-stock probability (e.g., if in-stock probability is 0.92, use z = 1.5 instead of z = 1.4). Round your answer to the nearest integer. d. Suppose it wants a 0.96 in-stock probability. What should its order-up-to level be?
