Six samples were collected from a production process, each with four units. The measures of those collected units are not provided. However, since you are given the mean and range for each sample, you do not need the detailed sample measures to solve the problem. Construct a 3 mean chart (X-bar chart) using Table 10.3 (Round all answers to three decimal places.) (1) The quality standard is (the center line): (2) The lower control limit is (LCL): Construct a 3 R chart: (3) The quality standard is (the center line): (4) The upper control limit is (UCL)
