You are given the below simple predictive model derived from a particular training data set Y = -100 + 50 X The testing data set is given as Y = (1000,1300,2000) X = (20,30, 40) One way to quantify the goodness of the model is to calculate the RMSE. The RMSE in this case equals: 0 A. 100 Q B. 57.8 O C. Can not be calculated with the given data. 0 D. 10000
