A local computer store is running a sale on the first 99 flat panel monitors it sells. There is an equal chance of 0–99 units being sold. Each monitor costs

$250 and makes a profit of $10 upon sale, that is, profit equals - +250 + +10X, where X = the number of monitors sold. The mean quantity that the store expects to sell is 49.5 units.

(a) Calculate the store’s expected profit.

(b) Simulate the sale of 10 flat panel monitors using the following double digit random numbers: 47, 77, 98, 11, 02, 18, 31, 20, 32, 90.

(c) Calculate the average profit in

(b) and compare it to the results of (a).
