Also, for problem 1 parts B and C, I am conceptualizing carrying the umbrella when the treatment threshold is less than the predicted risk. If so, I would plan to bring the umbrella based on both predictions which seems odd.
For problem 1 parts d and e, I am calculating the predicted risk for rain for channel 3 and weighted the predictions based on the number of days the risk applied to. When I do this my numbers look strange. Am I overthinking this question?
