Question 20 We are planning for our annual marketing campaign to reach our desired respondents. Based on data that we have collected; we trained a classification model. After we calculated the predicted event probabilities from the model, we put respondents into ten deciles. The deciles are determined in descending order of the probabilities. Because of privacy concerns, we cannot give you access to the original data. Instead, we provide you the following table. Our desired respondents are labelled Event. Decile of Predicted Number of Respondents Event Probabilities Event Non-Event 873 454 1 94 1234 2 121 1206 90 1238 4 135 1192 5 121 1207 6. 124 1204 7 100 1227 8. 55 1273 1327 Our campaign goal is to reach as many respondents as possible. To use our resources wisely, we only want to reach respondents who will at least twice more likely to respond than the overall sample. Therefore, we need to determine the maximum percent of respondents that we should reach. In what deciles the respondents are in should we reach? Multiple Choice: (A) Decile 0 (B) Decile 0 and Decile 1 (C) Decile 0, Decile 1, and Decile 2 (D) Decile 0, Decile 1, Decile 2, and Decile 3 (E) Decile 0, Decile 1, Decile 2, Decile 3, and Decile 4
