The table on the right examines the number defects associated with different levels for processing widgets. For example, when the processing speed reaches 60 widgets per hour, an average of 65 defects are encountered. Draw a scatter diagram showing the relationship between processing speed and defects. What conclusions can you derive from the diagram?
Units Processed per hour Average number of defects
300 50
400 42
500 40
600 55
700 80
800 95
