A quality control inspector has taken four samples with five observations each at the Beautiful Shampoo Company, measuring the volume of shampoo per bottle. If the average range for the four samples is 0.4 ounces and the average mean of the observations is 20.1ounces, develop 3-sigma control limits for the bottling operation. (Round answers to 2 decimal places, e.g. 15.25.)

Ten samples with five observations each have been taken from the Beautiful Shampoo Company plant in order to test for volume dispersion in the shampoo bottle-filling process. The average sample range was found to be 0.5 ounces. Develop control limits for the sample range. (Round answers to 3 decimal places, e.g. 15.250.)
