Demand for walnut fudge ice cream at the Sweet Cream Dalty can be approximated by a normal distribution with a mean of 17 gallons per week and a standard deviation of 32 gallons per week. The new manager desires a service level of 90 percent Lead time is two days, and the dairy is open seven days a week (Hint Work in terms of weeks.) Use Table B and Table B1 a-1.

Answer is complete and correct. ROP 7.05 gallons a-2. How many days of supply are on hand at the ROP, assuming average demand? (Do not round intermediate calculations. Round your final answer to 2 decimal places.) Answer is complete and correct. Days 286 b-1. If a fixed-interval model is used instead of an ROP model, what order size would be needed for the 90 percent service level, with an order interval of 7 days and a supply of 8 gallons on hand at the order time? (Do not round intermediate calculations. Round your final answer to the nearest whole number.) Answer is complete but not entirely correct. Order 35 gallons b-2.
