S2 Topic 1: Binomial and Poisson distributions
True or false backmore
Check some basic facts on Binomial and Poisson distributions by completing this true-false test. You can only Reset the scores once you have correctly answered all 10.
Correct: Attempts: % Correct:
1 For a Binomial distribution there must be a fixed number (n) of trials
True False
2 For a Binomial distribution the probability of success (p) can vary from trial to trial
True False
3 For a Binomial and a Poisson distribution the events must occur independently of each other
True False
4 A Binomial distribution is never symmetric
True False
5 A Poisson distribution can provide a good approximation to the Binomial distribution
True False
6 Trials in a Binomial distribution have only two outcomes: success or failure
True False
7 In a Poisson distribution, events can occur singly or at the same time
True False
8 In a Poisson distribution, events occur at a constant rate, given by the parameter l
True False
9 The number of heads and tails when spinning a coin is a good example of a Poisson distribution
True False
10 The number of cars passing a road junction in a five minute period is a good example of a Binomial distribution
True False
