The number x of people entering the intensive care unit at a particular hospital on any one day has a Poisson probability distribution with mean equal to five persons per day. (a) What is the probability that the number of people entering the intensive care unit on a particular day is two? (Round your answer to three decimal places.) What is the probability that the number of people entering the intensive care unit on a particular day is less than or equal to two? (Round your answer to three decimal places.) (b) Is it likely that x will exceed 10? Explain. O Yes, x is less than 2 standard deviations above the mean. O No, x is more than 2 standard deviations above the mean. You may need to use the appropriate appendix table or technology to answer this question.
