a fish distributor is trying to perfect his business to maximize the money he saves. daily fish sales are normally distributed with a mean of 250 and standard deviation of 30. the distributor sells each fish for $4.50 and pays $1.65 to buy each fish. the distributor must get rid of unsold fish by paying a waste removal facility fee of $0.25 per fish. how many fish should the distributor order each day and what % of the time will he experience a stock-out? are there any drawbacks to the order size proposed and how could the fisherman address such issues?
