The number of emails that I get in a weekday can be modeled by a Poisson distribution with an average of 0.2 emails per minute. What is the probability that I get no emails in an interval of length 5 minutes? What is the probability that I get more than 3 emails in an interval of length 10 minutes? 3. a) b)

On an average weekend, I get three emails from students. I am interested in X, the random variable of the number of emails from students I will get this weekend. 1. What family of distributions does this situation belong to? What is (are) the parameter(s)? 2. What is the probability that I get one email, ?(?=1)? 3. What is the probability that I get 5 or less emails, ?(?≤5)? 4. I estimate that I will be able to answer all...

Suppose the number of emails sent from a system follows the Poisson distribution, which averages 30 times per hour. a. Find the probability that an email will not be sent for a certain minute. b. Let T be a random variable that represents the time between when an email is sent and the next email is sent., Find the probability distribution of T and use this to determine the probability of more than 10 minutes of time between when an...

(b) The number of emails arriving at a server per minute is claimed to follow a Poisson distribution. To test this claim, the number of emails arriving in 70 randomly chosen 1-minute intervals is recorded. The table below summarizes the result. Number of emails 0 1 | 2 > 3 Observed Frequency 13 22 23 12 Test the hypothesis that the number of emails per minute follows a Poisson distribution? Use a significance level of a = 0.05. [7 marks]

8. Assume that the number of student complaints that arrive at dean's office can be modeled as a Poisson random variable. Also assume that on the average there are 5 calls per hour. a) What is the probability that there are exactly 8 complaints in one hour? b) What is the probability that there are 3 or fewer complaints in one hour? c) What is the probability that there are exactly 12 complaints in two hours? d) What is the...

The average number of customers arriving at a drive-through window of a bank branch is 39 per hour during lunch hours. Use X to denote the number of arrivals in a 5 minute time interval. Assume the customers arrive independently and the number of arrivals within each 5 minutes follows a Poisson distribution. Keep at least 4 decimal digits if the result has more decimal digits.
