c. A telecom company has developed a classifier for detecting whether a cell-phone network base station is faulty or not. We evaluate the classifier on a test set. Here is the confusion matrix. (In the table, F means faulty and NF not faulty.) i. Compute the accuracy of the classifier. ii. What is the accuracy of a majority-class baseline? (The class not faulty is the most common in the training set.) ii. Would you say that the classifier is more useful than the majority-class baseline? Explain why or why not
