quality control You are a quality manager in Infinity automotive company, and you are in the processof setting-up a Shewhart control chart, and you have collected five samples from theproduction line, where n= 5. Based on control chart rules you should collect at least20 samples to determine X-bar and R-bar, which will become the center line of yourchart, but you have decided to cut-corners and are planning to base your chart on onlythese five samples. Calculate the value of X-bar and R-bar of these five samples. Thesamples data collected from the production line is given in Table Q4.1. Note n = 5.
