my Work Given this information: Expected demand during lead time = 275 units Standard deviation of lead time demand = 14 units Use Table Determine each of the following, assuming that lead time demand is distributed normally: a. The ROP that will provide a risk of stockout of 1 percent during lead time. (Round your answer to the nearest whole number.) ROP units b. The safety stock needed to attain a 1 percent risk of stockout during lead time. (Do not round intermediate calculations. Round your answer to the nearest whole number.) Safety stock units c-1. Would a stockout risk of 2 percent require more or less safety stock than a 1 percent risk? Less More Suppose that the manager of a construction supply house determined from historical records that demand for sand averages 47 tons. In addition, suppose the manager determined that demand during lead time could be described by a normal distribution that has a mean of 47 and a standard deviation of 4 tons. Answer the following questions assuming that the manager is willing to accept a stockout risk of no more than 3 percent. Use Table B.2 (Round your answer to two decimal points.) a. What value of z is appropriate? Z-Value b. How much safety stock should be held? (Round your answer to two decimal points.) Safety Stock Regional Supermarket is open 365 days per year. Daily use of cash register tape averages 18 rolls. Usage appears normally distributed with a standard deviation of 2 rolls per day. The cost of ordering tape is $1.50, and carrying costs are 42 cents per roll a year. Lead time is 2 days. Use Table and Table2. a. What is the EOQ? (Round your answer to the nearest whole number.) EOO b. What ROP will provide a lead time service level of 99.8 percent? (Round up your answer to the nearest whole number.)
