You're building a new attention classifier for Zoom (a cloud platform for video and audio conferencing) because of kids not paying attention during online classes. So you're creating a scoring mechanism. For testing the classifier’s performance, you collected 1000 test records in total. 30 out of 500 tests, the classifier issued a warning (no attention) even when a student is paying attention in a meeting: so, a warning (no attention) was correctly issued 370 times. But 50 out of 500 times, there was no warning when a student was not paying attention. Please fill out a confusion matrix (A to H) below based on the information you collected.
