The mean number of daily surgeries at a local hospital is 6.2. assume that surgeries are random, independent events. (a) the count of daily surgeries follows approximately: a poisson distribution with mean 6.2 and standard deviation 2.49. a binomial distribution with mean 6.2 and standard deviation 3.1. a binomial distribution with mean 6.2 and standard deviation 1.76. a binomial distribution with mean 6.2 and standard deviation 3.8. a poisson distribution with mean 6.2 and standard deviation 6.2. (b) the probability that there would be only 2 or fewer surgeries in a given day is approximately (round to 4 decimal places):

1)  Poisson distribution with mean 6.2 and standard deviation 2.49.

2) 0.0536

Step-by-step explanation:

We are given the following information in the question:

Mean of daily surgeries = 6.2

a) The count of daily surgeries can be treated as a Poisson distribution.

Variance = 6.2

Standard deviation =

a) Poisson distribution with mean 6.2 and standard deviation 2.49.

2) P( 2 or less surgeries)

Formula:

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
