Coffee Machine A vending machine that dispenses coffee
Chapter 13, Problem 13.1.261(choose chapter or problem)
Coffee Machine A vending machine that dispenses coffee does not appear to be working correctly. The machine rarely gives the proper amount of coffee. Some of the time the cup is underfilled, and some of the time the cup overflows. Does this variation indicate that the mean number of ounces dispensed has to be adjusted, or does it indicate that the standard deviation of the amount of coffee dispensed by the machine is too large?
