McDaniel Shipyards wants to develop control charts to assess the quality of its steel plate. They take ten sheets of 1" steel plate and compute the number of cosmetic flaws on each roll. Each sheet is 20' by 100'. Based on the following data, develop limits for the control chart, plot the control chart, and determine whether the process is in control. ​ Sheet Number of    flaws 1 1 2 1 3 2 4 0 5 1 6 5 7 0 8 2 9 0 10 2
