After final assembly and painting, the parts areplaced on a conveyor belt that moves the parts past a final inspection station. How fast the parts move past the final inspection station depends upon the linespeed of the conveyor belt (feet per minute). Although faster line speeds are desirable, management is concerned that increasing the line speed too much maynot provide enough time for inspectors to identify which parts are actually defective. To test this theory, Brawdy Plastics conducted an experiment in which thesame batch of parts, with a known number of defective parts, was inspected using a variety of line speeds. The following data were collected.Excel file: data14-05.xlsxNumber ofLineDefectiveSpeedParts Found20232021301930164015401750145011If requiredonter
