The manager of a bottling plant is anxious to reduce the variability in net weight of fruit bottled. Over a long period the standard deviation has been 15-2 gm. A new machine is introduced, and the net weights (in grams) in randomly selected bottles (all of the same nominal weight) are 987, 966, 955, 977, 981, 967, 975, 980, 953, 972. Would you report to the manager that the new machine has a better performance?
