A machine can be adjusted so that under control, the mean amount of sugar filled in a bag is 5 pounds. To check if the machine is under control, six bags were picked at random and their weights (in pounds) were found to be as follows:

5.4 5.3 4.9 5.3 4.9 5.4

Assume that the weights of sugar bags are normally distributed.

		1.03
		2.06
