Table of Control Chart Constants a) Centreline = b) LCL = UCL = c) Can we conclude that the process mean is out of control based on the following data representing one of the samples selected? Hint: Check if the sample mean is outside control limits. 179.89 179.85 180.64 183.63 183.65 183.25 182.37 179.85 180.29 179.67 179.30 181.90 183.04 181.55 Download CSV O No O Yes
