Open self-quiz 6; Multiple Linear Regression
Operators (2, 3, 4, 5, 6)
Operators (2, 3, 4, 5, 6)
Rpm (70, 60, 50, 40, 40)
Waste (0.06, 0.04, 0.08, 0.09, 0.03)
Note: The questions below ask about “temperature”, while the data includes “rpm” and “waste”. It is assumed that “rpm” is meant in place of “temperature”, and that “waste” is the dependent variable.
1. Determine the slope of the line for the # operators
2. Determine the slope of the line for the temperature
3. Determine the Y intersection
4. Determine Coefficient
5. Conclusion
o Relationship with positive slope
o Strong linear relationship
o No linear relationship
o None
o Relationship with positive slope
o Strong linear relationship

6. Determine experimental value of F
7. Determine critical value F
8. Conclusion based the ANOVA
o Relationship with positive slope
o Strong linear relationship
o No linear relationship
o None
o Relationship with positive slope
o Strong linear relationship
o No linear relationship
o None
