The supervisor of a manufacturing processs believed that assembly line speed (in feet/min) affected the number of defective parts found during on-line inspection. To test this theory, management had the same batch of parts inspected visually at a variety of line speeds. The following data were collected. a. Does the data support the theory? b. Develop the estimated regression equation that relates line spped to the number of defective parts found. c. use the equation developed to forecast the number of defective parts found for a line speed of 50 feet per minute. (use Formula, graphical and tools>data analysis and make sure you get the same results) D. Use Minitab to solve & graph Line Speed #Defective Parts 20 21 20 19 40 15 30 16 60 14 40 17
