The model saves 1 hour for each correct prediction.

I vaguely recall that we should multiply the true positives by the hours saved and the false negatives by the hours lost. I hope I remember the right numbers!

I think if we calculate the total hours saved and lost, we can find the net impact. But I'm a bit confused about how to weigh the hours differently for correct and incorrect predictions.

This question feels similar to one we practiced about cost-benefit analysis in model evaluation. I think I need to focus on the hours saved versus lost.

I remember we discussed how to calculate the net impact based on true positives and false negatives, but I'm not sure how to apply it here.
