Calculate the ima barchart and R.chart controllis b. Calculate the mean bar) and range for the following sample, which was taken from the same process at a later time item number 12 3 Weight 4.3 5.1 4.9 Based on this sample and the control chartimies that you calculated in partial is the process in control Wy or why not
