Mary Grant, a marketing manager of an online retailer, has built two predictive models for estimating the annual spending of new customers. Applying the models to the 100 observations in the validation data set generates the accompanying data file that lists the customers' actual spending and predicted spending. 0. Compute the ME, RMSE, MAD, MPE, and MAPE for the two predictive models Note: Round intermediate calculations to at least 4 decimol places and your final onswers to 2 decimal ploces. Negotive values should be indicoted by o minus sign. b. Are the predictive models over- or underestimating the actual selling price on average? c. Compare the RMSE and MAD of the two predictive models. Which predictive model performs better? d-1. Compare the better-predictive model to a base model where every customer is predicted to have the average spending of the cases in the training data set, which is $290. Compute RMSE for the base model. Note: Round intermediate colculations to at least 4 decimal places ond your final answer to 2 decimal places. d-2.
