Question

A. One could use either dependent variable with equal success in a regression. B. Regressing using the actual distance is the better option, because the residuals (graph at left) are smaller. C. The transformed dependent variable yields the best regression, because the residuals (graph at right) for this variable appear to be independent of the amount of gunpowder used in the shell. D. These residual plots show that neither dataset can be correctly described using a linear regression. E. All the above statements are wrong

Explanation / Answer

Answer: C. The transformed dependent variable yields the best regression, because the residuals (graph at right) for this variable appear to be independent of the amount of gunpowder used in the shell.
