a. Determine the Taguchi loss function. 

b. Given the nominal specification is 14 watts, determine the optimal tolerance level should the integrated circuit be manufactured.

Made4Us Inc. makes lithium battery for handheld computers. The factory requires all the products to conform a specification with no more than 14 = 0.1 watts at peak use. Exceeding these limits results in an estimated loss of $50. However, the manufacturer can adjust the wattage in the manufactoring process by changing the circuit at a cost of $4.
