Answer #1

We know that,

Poisson Distribution Formula le P(X= x) = x! where x = 0, 1, 2, 3, ... 2. = mean number of occurrences in the interval e = Eu

\lambda = 3 per 6 month case

P(X<2) = 0.19915

~ 0.1992

    The number of Emergency Room visits has increased over the past several years in the United States. One possible reason for this increase may be that people tend to postpone routine health care. This could result in more visits to the Emergency Room. Of all patients who visit an Emergency Room, suppose 22% are seen in less than 15 minutes, 13% are admitted to the hospital, and 5% are seen in less than 15 minutes AND admitted to the hospital....
