Taguchi Loss Function

Stahman, Inc., estimates its hidden external failure costs using the Taguchi loss function. Stahlman produces plastic sheets that vary in thickness and grade. For one of its large-volume products, it was determined that k = $40,000 and T = 0.28 inches in diameter. A sample of four units produced the following values:

Unit No.	Actual Diameter (y)
1	0.28
2	0.30
3	0.25
4	0.27

Required:

1. Calculate the average loss per unit. Round your intermediate calculations to six decimal places. If required, round your answer to the nearest cent and use the same in subsequent requirements. $________ per unit

2. Assuming that 140,000 units were produced, what is the total hidden cost?

$________

3. Assume that the multiplier for Stahmans hidden external failure costs is five. What are the measured external costs?

$________
