In a manufacturing process the assembly line speed (feet perminute)was thought to affect the number of defective parts foundduring the inspection process. To test this theory, managersdevised a situation in which the same batch of parts was inspectedvisually at a variety of line speeds. The collected the followingdata:
| Line Speed | Number of Defective Parts Found |
| 20 | 21 |
| 20 | 19 |
| 40 | 9 |
| 30 | 15 |
| 60 | 5 |
| 40 | 8 |
Use four digits of accuracy for your answers.Use the data todevelop an estimated regression equation that could be used topredict the number of defective parts found, given the line speed.What is the estimated regression model (Enter b0 and b1)? How muchof the variation in the number of defective parts is explained byyour regression model (R Square)?
1) b0 - Intercept
2) b1
3) R Square
