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 0.6 ounces and the average mean of the observations is 20.3 ounces, develop 3-sigma control limits for the bottling operation. (Round answers to 2 decimal places, e.g. 15.25.) CL 20.3 UCL 21.2462 LCL 19.9538 Question 3 of 5 0.17/1 = The Awake Coffee Company produces gourmet instant coffee. The company wants to be sure that the average fill of coffee containers is 12.0 ounces. To make sure the process is in control, a worker periodically selects at random a box of six containers of coffee and measures their weight. When the process is in control, the range of the weight of coffee samples averages 0.5 ounces. a) Develop an R-chart and an 7-chart for this process and answer the questions. b) The measurements of weight from the last five samples taken of the six containers follow: Sample I R 1 12.0 0.6 2 11.2 0.5 3 12.7 0.5 4 11.3 0.4 5 11.7 0.8 (a) Your answer is partially correct.

CL 0.56 Breeze Toothpaste Company has been having a problem with some of the tubes of toothpaste leaking. The tubes are packed in containers with 100 tubes each. Ten containers of toothpaste have been sampled. The following number of toothpaste tubes were found to have leaks: Sample Number of Leaky Tubes Sample Number of Leaky Tubes 1 6 6 16 2 10 7 6 3 11 00 8 4 13 9 4 5 00 10 9 Total 91 (a) Your answer is partially correct. Develop a p-chart with 3-sigma control limits: (If the lower control limit is negative, round the LCL to zero and round all other answer to 3 decimal places, e.g. 15.250.)
