4. An average of 3 patients arrives the emergency room of a hospital in a 10-minute time interval. According to the Poisson distribution in this period of time, a) What is the probability of one patient arrival? b) What is the probability of having at least 5 patient arrivals? Note: For any given arrival time, a discrete Poisson distribution can be established by using the formula P(x): for x = 0,1, 2,3, 4 .. x! where P(x) = probability of x arrivals x = number of arrivals per unit of time A = average arrival rate e = 2.7183

Consider a Poisson distribution with a mean of two occurrences per time period. Compute the probability of three occurrences in one time period (to 4 decimals). Compute the probability of seven occurrences in two time periods (to 4 decimals).
2 2 In a town 10 accidents take place in a span of 50 days. Assuming that the number of accidents follows the Poisson Distribution, find the probability that there will be 3 or more accidents in a day.
The number of accidents per day has the poisson distribution where the value of mean is 0.8. Determine: (i)The number of accidents within eight days that are selected at random.(ii)The probability that at least three accidents happened within eight days that are selected at random.(iii)The probability that less thank four accidents happen within twelve days that are selected at random.
Person P is walking with his dog every day. He decides to model the time intervals between dog encounters (i.e., how long does it take between two encounters) with the independent random variables Y₁, . . ., Yn . Number of dogs encounters per day, the number of customers entering a store per hour, the number of bacteria per liter of water, etc. are classically modelled using the Poisson distribution. With an exponential distribution, on the other hand, is used for modelling intervals of between events and how long a light bulb lasts, for example. After learning this, person P decides to model the observations in such a way that the corresponding random variables Y1,..., Yn for a random sample, that is, independent observation, of the exponential distribution Exp(1/µ), µ > 0. The parameter µ > 0 is used as the statistical model parameter 1 which is the expected value of each observation random variable Yi. (a) Form the maximum likelihood estimate μ^(y) in the model for the parameter μ…
The times between arrivals in a queue follow an exponential distribution with a rate of 1. Check the incorrect alternative: a) 50% of arrivals will take place before 1 minute. b) If the times between arrivals are exponentially distributed with a rate equal to 1, then arrivals occur according to a Poisson distribution with an average equal to 1. c) Times between arrivals are independent. d) The variance of the times between arrivals is equal to 1. e) There is an average of one arrival every minute.
