Which distribution would be most appropriate to describe the number of fatalities in Utah per year due to mountain climbing accidents? Binomial, Poisson, or Bernoulli?

Find the standard normal area for the following: P(0<Z<1.55).

Solution

Poission distribution is best fit for that as it can go to from 0 to infinity with mean = lembda.

P(0<Z<1.55) = P(z<1.55) -P(z<0)

P(0<Z<1.55) = 0.9394 - 0.5

P(0<Z<1.55) = 0.4394
