The allowable drift on a voltage regulator has a specification of 0.0 +- 0.8 volts. Each time a regulator does not satisfy this specification, there is an $80.00 cost for rework. a.) Write the expression for the Taguchi loss function and evaluate the coefficient. b.) If the PDF for the drift in volts is f(x) = (3/4)(1-x^2) lxl < 1 , f(x) = 0 lxl > 1 What is the expected value of the Taguchi loss? C.) With the PDF given in b, what fraction of the regulators do not meet the specifications?
