63. X control charts are used to maintain control of the manufacture of the cases used to house a generic brand of personal computer. Separate charts are maintained for length, width, and height. The length chart has UCL = 20.5 inches, LCL = 19.5 inches, and a target value of 20 inches. This chart is based on using subgroups of size 4 and three- sigma limits. However, the customer's specifications require that the target length should be 19.75 inches with a tolerance of ±0.75 inch. What percentage of the cases shipped will fall outside the customer's specifications?

Part 3 Lower Control Limit (LCLx)=enter your response here units (round your response to two decimal places). Part 4 b) Now determine the 2-sigma x-chart control limits. Upper Control Limit (UCLx)=enter your response here units (round your response to two decimal places). Part 5 Lower Control Limit (LCLx)=enter your response here units (round your response to two decimal places). Part 6 How do the control limits change? A. The control limits are tighter for the 3-sigma x-chart than for the 2-sigma x-chart. B. The control limits for the 2-sigma x-chart and for the 3-sigma x-chart are the same. C. The control limits…
A large beverage company would like to use a statistical process control to monitor how much liquid beverage it puts into each bottle. The company operated its bottle filling line under careful supervision, confident that the line was under complete control, for seven hours. Each hour, a sample of 20 bottles was taken off the line and the amount of liquid in each bottle was carefully measured. This is the resulting data: Sample Sample Sample Mean (ml) Range (ml) No. #1 350.4 0.5 349.6 0.5 #3 349.6 0.7 # 4 349.5 0.4 #5 349.8 0.5 #6 350.4 0.9 #7 349.8 0.3 Which of the following is closest to the upper control limit on the beverage company's range chart?
