Assume the specifications for a part (in inches) are 8.00 ± 0.37, and the Taguchi loss function is estimated to be L(x) = 8,000(x − T)2. Use the Excel template Taguchi to determine the estimated loss if the quality characteristic under study takes on a value of 8.54 inches. Round your answer to the nearest cent.
The Canine Gourmet Company produces delicious dog treats for canines with discriminating tastes. Management wants the box-filling line to be set so that the process average weight per packet is 47 grams. To make sure that the process is in control, an inspector at the end of the filling line periodically selects a random box of 8 packets and weighs each packet. When the process is in control, the range in the weight of each sample has averaged 7 grams. Click the icon to view the table of factors for calculating three-sigma limits for the x-chart and R-chart. a. Design an R- and an x-chart for this process. The UCLR equals grams and the LCLR equals grams. (Enter your response rounded to two decimal places.)
