QUESYION 21 Your friend used a different cut-off probability and built the following confusion matrix, For the remaining questions on this exam, use your friend's matrix given below. Prediction 0 1 Total 0 424 1215 1639 Actual 1 198 182 380 Total 622 1397 2019 Answer the following questions based on your friend's confusion matrix i What is the misclassication error rate? (Answer format: 0.xx) u According to your friend's confusion matrix. how many patients are correctly predicted as "no-show's\"? m Among the patients who did no miss the appointment what is the proportion of patients who are predicted as "no-show's"? (Answer format: 0.xx) Qumran 22 Supposed the clinic is trying to reduce its losses due to "no-show" patients and plans to double-book an appointment if the model is predicting a "no-show" (ire. schedule another patient at the same appointment time) . For simplicity, let's assume that all double-booked patients show up. On the other hand, if the model fails to predict a "no-show\" beforehand. the clinic will miss its chance to schedule another patient instead and lose revenue. You are asked to adjust the model so that the clinic could minimize the chance of loosing revenue due to "no-shows'i In other words, the clinic would like to correctly predict all "no-show's'i Are the following statements true or false? A If the cut-off probability is 0, all actual "no-show" patients will be correctly classied/predicted as "no-shows" a If the cut-off probability is 1, all actual "no-show" patients will be correctly classied/predicted as "no-shows" c Your friend should lower the cut-off probability to achieve the clinic's objective 0 Your friend should increase the cut-off probability to achieve the clinic's objective ' only B, and C. are FALSE ' All statements are FALSE ' only C. is TRUE ' onlyA. and C, are TRUE
