The number of rescue calls received by a rescue squad in a city follows a Poison distribution with mean (ú) = 2.83 per day. The squad can handle at most 4 calls a day. A) what is the probability that the squad will be able to handle all the calls on the particular day . B) The squad wants to have at leat 95% confidence of being able to handle all the calls received in a day. At least how many calls a day should a squad be prepared for? C) Assuming that the squad can handle at most 4 calls a day, what is the largest value of ú that would yield 95% confidence that the squad can handle all calls?
