Describe the coefficient of at least one variable while the other variable(s) are in the model. Hint: This is a change in y with a change in x. Include a plot of the residuals for your model. Determine whether the assumptions for regression have been satisfied. At the end... Provide an appendix with the ANOVA ( at the top just move it down) table and Regression Output (also at the top) (table with coefficients and p-values for model) • Logistics - Include a Title page. Check spelling and grammar. Include neat plots
