Refer to the exhibit:An analyst examined logistic regression models for predicting whether a customer would make a purchase. The ROC curve displayed summarizes the models.Using the selected model and the analyst's decision rule, 25% of the customers who did not make a purchase are incorrectly classified as purchasers.What can be concluded from the graph?
