Four samples were collected from a production process, each with five units. The measures of those collected units as well as sample means and ranges are given below. The details of the last sample are deliberately removed. Since you are given the mean and range for each sample, you do not need the detailed sample measures to solve the problem. That's all you need to proceed. 1 2. 3 4 1 50.91 50.57 51.45 2 50.82 50.02 51.91 3 52 51.06 50.29 4 51.57 51.06 51.21 5 50.80 51.35 50.71 X-bar 51.22 51.01 51.11 52.4 Range 1.20 0.78 1.62 1.1 Construct a 3o mean chart (X-bar chart) using Table 10.3 (Round all answers to two decimal places.)
