Assume the weekly demand for flip-chart block at B&M to be normally distributed, with a mean of 2,500 units and a standard deviation of 500 units. The manufacturer takes two weeks to fill an order placed by the B&M manager. The store manager currently orders 10,000 flip-chart blocks when the inventory on hand drops to 6,000 units.

Tell me what percentage shtock-out and no stock out ?

Please use mean, standard deviation and Z-table. My professor said 92.07% no stock out. 7.93% Stock out, but I don't get how those numbers came up.

Show me the graph if you can.

Thank you so much in advance
