Reducing scrap of 4foot planks of hardwood is an important factor in reducing cost at a woodflooring 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 undei the old and new methods. Sixty-three of the 600 planks were scrapped under the old method, whereas 33 of the 500 planks were scrapped under the new method. {You may find it useful to reference the appropriate table: 2 table or t table) a. Construct the 95% confidence interval for the difference between the population scrap rates between the old and new methods, respectively. (Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and nal answers to 2 decimal places.) a Answer is complete but not entirely correct". ligandenoelntewal 0.019% to I guess
