An Important Part of Any Dispensing Process Is Statistical Quality

question 3

Essay

An important part of any dispensing process is statistical quality control. At the Billy Goat Gruff Inn, machines are set to dispense 600 ml of soda into every customer's glass. Over time, however, the machine can get "out of control" and dispense too much soda or too little. At a random point in time each clock hour, the owner dispenses and checks a glass of dispensed soda and determines the actual volume of soda dispensed. One day the volumes of the dispensed soda were:
600.15, 599.92, 599.85, 599.92, 599.81, 600.14, 600.04, 599.98
Is there sufficient evidence to conclude that the dispensing machine needs some adjustment?
