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:central line = d2?, UCL = D2?, LCL = D1?(The values of d2, D1, and D2 are found in the table of control chart factors). In a bottling factory, after bottling, the volume of juice in seven sample bottles is checked every 30 minutes. For this process,
