Bottles for room spray are supposed to weigh exactly 16 oz. Inspectors want to develop process control charts. They take o7 boxes of five bottles each and weigh them. They obtain the following data. The mean weights of each of the 07 samples are 14.6,16.5,18.1,13.2,16,15.9, and 14.8 respectively. Likewise, the range values for the each of 07 samples are o.7,0.5, 0.4,0.2,0.4,0.5, and o.9 respectively. Ebr the X-bar charts and R-charts, the Parameters, A2, D3 and D4 are respectively.

A critical part has a manufacturing specification of 4.5 cm ± 0.10. If this measurement is larger than 4.6 or smaller than 4.4, the product fails at a cost of $150.a. Calculate the k value for Taguchi loss function. What is the Taguchi loss function for this part?b. Using the above Taguchi loss function, determine the estimated loss for when the actual part dimension is 4.46 cm.
