rink dispenser is designed to dispense 250 mL of drink per cup. However, there have been recent reports to the managements of a fast-food restaurant of both underfilled and overfilled cups. Seeking to investigate this matter, they fill up 50 cups using this machine. If the mean amount of drink in the 50 cups is 248 mL with standard deviation of 12 mL, is there a cause for concern for the management? Use a level of significance of
