Bottles for room spray are supposed to weigh exactly 16 oz. Inspectors want to develop process control charts. They take o7 boxes of five bottles each and weigh them. They obtain the following data. The mean weights of each of the 07 samples are 14.6,16.5,18.1,13.2,16,15.9, and 14.8 respectively. Likewise, the range values for the each of 07 samples are o.7,0.5, 0.4,0.2,0.4,0.5, and o.9 respectively. Ebr the X-bar charts and R-charts, the Parameters, A2, D3 and D4 are respectively.
