Bottles for room spray are supposed to weigh exactly 16 oz. Inspectors want to develop process control charts. They take six boxes of five bottles each and weigh them. They obtain the following data. The mean weights of each of the 6 samples are 15.43, 14.47, 18.07, 17.34, 12.74, and 15.58 respectively. Likewise, the range values for the each of 6 samples are 1.63,0.66, 0.47,0.40, 0.20, and 0.90 respectively.
