Five samples of size 4 were taken from a process. A range chart was developed that had LCLr = 0 and UCLr = 2.50. Similarly, an average chart was developed with the average range from the five samples, with LCLx = 15.0 and UCLX = 24.0. The ranges for each of the five samples were 1.75, 2.42, 2.75, 2.04, and 2.80, respectively. The values of the sample average for each sample were 19.5, 22.3, 17.4, 20.1, and 18.9, respectively.
