A product is supposed to weigh exactly 82 grams. Inspectors want to develop process control charts to support quality assurance. They take four samples (k=4) of two hundred products (n=200) and weigh them. If the standard deviation (sigma) is 0.1 grams for the production the product and the control limits are set at 3 standard deviations (z=3), what is the Upper Control Limit (UCL)? The x-barbar=81.98 and the Sigma- x-bar =0.007071. a. 82.00121 b. 82.0435 C. 82.3755 d. 82.2348 e. 82.00847
