Question
entering the intensive care unit at a particular hospital on any one day has a Polsson probability distribution with mean equal to five persons per day. ty that the number of people entering the intensive care unit on a particular day is two? (Round your answer to three decimal places.) 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 107 Explain Yes, x is less than 2 standard deviations above the mean e No, x is more than 2 standard deviations above the You may need to use the appropriate appendix table or technology to answer this questionExplanation / Answer
Solution:-
= 5
= sqrt(5)
= 2.2361
a) The probability that the number of people entering the intensive care unit in a particular day unit is two is 0.08422.
x = 2
By applying poisons distribution:-
P(x; ) = (e-) (x) / x!
P(x = 2) = 0.08422
b) The probability that the number of people entering the intensive care unit in a particular day unit is less than or equal to 2 is 0.12465
x = 2
By applying poisons distribution:-
P(x; ) = (e-) (x) / x!
P(x < 2) = 0.12465
c) No, x is more than 2 standard deviations above mean.
