A small retailer is considering various monthly plans for purchasing electricity. They can pre-purchase kWhs at the cost of 4.5 cents per kWh.  If they don’t use all of the kWhs they purchase, then there is no refund for the unused electricity. If they need more kWhs than they purchase, the extra kWhs are purchased at the rate of 6 cents per kWh.  Their forecast for kWh usage per month is normally distributed with a mean of 6000 and a standard deviation of 2500. What is the cost of over-estimation?  

Kick Flip Inc. makes skateboard decks for specialty skateboard stores. The production process of the skateboard decks is done in batches and consists of the 3 steps shown in the figure below. The size of each batch is 20 decks and demand is one batch per hour. In the first stage the raw material is sanded. This step takes 3 minutes per deck. After this step, the decks are painted using a Lithography machine. This step takes 2 minutes of production time per deck. The decks are then loaded onto a pallet and dried quickly using an ultraviolet lamp. The lamp can dry up to 20 decks at one time. Drying takes 30 minutes. Each state (i.e., sanding, painting, and drying) has one operator. What is the capacity of the “Painting” stage in batches?
