Question: An important part of any dispensing process is statistical quality control. At the Billy Goat Gruff Inn, machines are set to dispense 600ml of soda into every customer’s glass. Over time, however, the machine can get out of control & dispense too much soda or too little. At a random point in time each clock hour, the owner dispenses & checks a glass of dispensed soda & 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 adjustments? Use α = 0.05 to make a conclusion.
