Find the indicated control limits.For a production process for which there is a great deal of data since its last modification, the population mean ? and the population standard deviation ? are assumed known. For such a process we have the following values for an R chart:  (The values of d2, D1, and D2 are found in the table of control chart factors).In a chalk-producing factory, after production, the length of six sample pieces of chalk is checked every 15 minutes. For this process, ? = 3.73 in. and ? = 0.15 in. Find the central line, UCL, and LCL for the range.
