Someone claims that the number of hits on his website has a Poisson distribution with mean three per half an hour. We would like to observe the website statistics during a period of two hours to figure out the number of hits during this period a)Define the random variable of interest, its support, and parameter values over this period b)What is the probability that number of hits will be at least 10 over this period
Problem 1: 10 points Assume that a random variable X follows the Poisson distribution with intensity-A, that is k! for k 0,1,2, . Using the identity (valid for all real t) exp(t) = Σ冠. k! k=0 derive the probability that X takes an even value, that is PIX is even
Exercise 2.23 If X is a discrete random variable having the Poisson distribution with parameter that the probability that X is even is e cosh A. Exercise 2.24 If X is a discrete random variable having the geometric distribution with parameter p. show that the probability that X is greater than k is (1 -p)k à, show
Recall that a discrete random variable X has Poisson distribution with parameter λ if the probability mass function of X Recall that a discrete random variable X has Poisson distribution with parameter λ if the probability mass function of X is r E 0,1,2,...) 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 computation that the mean of...
