The following data represents sample data of $6$ oz$.$ bottles of after$-$shave. Develop the X$-$bar and R control charts for the following sample. A process that is considered to be in control measures an ingredient in ounces. Below are the samples taken from the process. Assuming the population standard deviation $\backslash$sigma $=2.$
