A videо-streаming service is chооsing between TWO logistic regression models to flаg subscribers likely to cаncel their subscription this month. Each missed cancellation costs the company about $40 in lost subscription revenue. Each wrongly-flagged subscriber costs about $3 — the cost of sending them a retention email they didn't need. Both models were evaluated on 2,000 subscribers, 200 of whom actually cancelled: MODEL A: TN = 1770, FP = 30, FN = 120, TP = 80 MODEL B: TN = 1600, FP = 200, FN = 20, TP = 180 In 2-3 sentences, which model should the streaming service deploy, and why? Cite specific numbers from the confusion matrices and tie your argument to the relative costs above.
