This output is generated by the regression routine in Excel, and is similar to what would be produced by M For HW7, you will learn the math behind how these numbers are generated and recreate this output. The Week 8 notes, especially 8-3, will give you the equations for each cell. Your answers will go below, though you will need additional cells for calculations. Each cell should have a function or equation- not just a number. The result should match the output to the right, so you can easily check your work. Part a. Fill in the yellow cells below. These must all be functions or equations. Do n Regression Statistics Multiple R R Square Standard Error Observations ANOVA df SS MS F Regression Residual Total

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
