I’m working on a writing report and need an explanation and answer to help me learn.
In a manufacturing process the assembly line speed (feet per minute) with thought to affect the number of defective parts found during the inspection process. To test this theory, managers devised a situation in which the same batch of pots was inspected visually at a variety of line speeds. They collected the following data (see file).
Instructions:
- Develop a scatter chart with line speed as the independent variable. What does the scatter chart indicate about the relationship between the line speed and the number of defective parts found?
- Use the data to develop an estimated regression equation that could be used to predict the number of defective parts found, given the line speed. What is the estimated regression model?
