Based on the model evaluation results, why is this a viable model for production?
  1. The model is 86% accurate and the cost incurred by the company as a result of false negatives is less than the false positives.
  2. The precision of the model is 86%, which is less than the accuracy of the model.
  3. The model is 86% accurate and the cost incurred by the company as a result of false positives is less than the false negatives.
  4. The precision of the model is 86%, which is greater than the accuracy of the model.
