Consider the following regression results: Describe how the response y depends on the regressor x. What is the formula for the regression line? What is the B0 and B1, and what do these coefficients represent? The Residuals vs. fitted plot is used to assess what assumption? What does the above plot tell you about your data? (remember to round all answers to 3 decimal places) Call: Im(formula = y ~ X, data = d) Residuals: Min 1Q Median 3Q Max...
