Cartons of Plaster are supposed to weigh exactly 32 ounces. Inspectors want to develop process control charts. They take five samples of six (6) boxes each and weigh them. Sample means (X-bar) are: 33.8, 34.6, 34.7, 34.1, and 34.2 respectively. Also, the corresponding ranges are: 1.1,0.3, 0.4, 0.7, and 0.3, respectively. The lower and upper control limits of the xbar-chart are. respectively O a. 30.11 and 40.15 O b. 34.01 and 34.55 O C. 37.01 and 39.23 O d. 33.12 and 34.12 O e. None is correct
