An R's ROC curve with AUC = 0.9453 is presented below from an analysis on potential increased membership level from current basic members at Costco Wholesale. What does the AUC indicate on the prediction on increased membership enrollment among current base members?
A) The high AUC indicates an anomaly in that it requires data smoothing to match the baseline.
B) The high AUC indicates the KNN model performs well and better than the baseline model.
C) The high AUC indicates the KNN model is not predicting the level increase based on the baseline model.
D) The high AUC indicates there is a 0.05% probability the KNN model performs as predicted.
