Required:
(1)What is the adjusted budget for appraisal costs,assuming the new method is implemented and 800,000 units are tested during the manufacturing process in 2010?
(2)How much do internal failure costs change,assuming 600,000 units are tested under the new method and it reduces the amount of unacceptable units in the manufacturing process by 40 percent?
(3)What would be the change in the external failure budget,assuming external failures are reduced by 60 percent,assuming the same facts as in part (b)?
