Solidtronic, Inc., an OEM manufacturer, has a product specification of 81 +/ 5. The cost for warranty services is estimated as $425 per unit.

What is the value of k, the cost coefficient, in the Taguchi loss function for this situation?

Calculate the estimated total cost when the measured quality characteristic, x (e.g., circumference, measured in inches), is 84.

What is the expected loss (cost) per unit if the manufacturing process is centered on the target specification with a standard deviation of 2?
