Reducing scrap of 4-foot planks of hardwood is an important factor in reducing cost at a wood-flooring manufacturing company. Accordingly, engineers at Lumberworks are investigating a potential new cutting method involving lateral sawing that may reduce the scrap rate. To examine its viability, samples of 600 and 500 planks, respectively, were examined under the old and new methods. Sixty-three of the 600 planks were scrapped under the old method, whereas 30 of the 500 planks were a. Construct the 99% confidence interval for the difference between the population scrap rates between the old and new methods, respectively.
