Problem 2. Recall that a discrete random variable X has Poisson distribution with parameter λ if the probability mass function of X is fx (x) = e-λ- XE(0, 1,2, ) ar! This distribution is often used to model the number of events which will occur in a given time span, given that λ such events occur on average a Prove by direct cornputation that the mean of a Poisson randoln...

In each of the summer months (June, July, August), the number of accidents per months at a busy intersection is Poisson distributed with mean 1.5 accidents/month. For all other months, the number of accidents is Poisson distributed with mean 0.5 accidents/month. 7. a) (3 pts) First, let Y an, YFeb, YMar,... be the number of accidents occurring in the months of January, February, March, etc. Define a variable A- the total number of accidents occurring in the second half of...

Question C
C. Suppose that during each minute there is a 1 in 500, 000 probability that there is an accident at a particular intersection (independently of all other minutes). Using the approximation of 500,000 minutes per year, we expect to see 1 accident per year on average. One year somebody proposes to install a new kind of stoplight to reduce accidents. You believe a priori that there is a 1/5 chance that the new stoplight is effective, in which...

It is proposed to model the onset of hurricanes anywhere in the Gulf of Mexico as a Poisson process. The rate of occurrence, however, depends strongly on the month of the year. Specifically, we assume that hurricanes occur in only three months of the year: August, September, and October. During these months, the mean hurricane occurrence rate per month is as follows: Month Mean occurrence rate August 1.0 event per month September 2.0 events per month October 1.0 event per...
