d. Fit the regression models, CEO Pay vs Sales and Log CEO Pay vs Log Sales, including the Normal Probability Plots of the Residuals and the Residuals plots. What do these plots tell you about the two models? e. XYZ had 2021 sales of $5 billion. They wish to set their CEO Pay based on the one of the regression models above. For each model, calculate the projected CEO Pay based on sales of $5 billion. f. More specifically, XYZ wants their CEO Pay to be within the 95% confidence interval for average CEO Pay for public companies with $5 billion in sales. Given this, which of the models should they use to set the CEO Pay. (Consider the residual plots and the prediction output on the following page.)
