Probability Distributions resources

. 1. Given descriptions of 3 random variables, decide whether or not each is from a Poisson or Binomial distribution. 2. Application of the Poisson distribution given expected number of events per interval. Finding probabilities using the Poisson distribution. 3. Application of the binomial distribution given probabilities of success of an event. Finding probabilities using the binomial distribution. 4. Given a random normal variable X as N(m, var) find P(X > a),a > m; P(X < b), b < m. 5. Given uniform distribution X, calculating the expectation and variance. Also finding P(X=a) for a given value a.6. Question on the exponential distribution involving a time intervals and arrivals application, finding expectation and variance. Also finding the probability that a time interval between arrivals is less than a given period. All parameters and times randomised.

These slides are aimed to be used in a workshop to train mathematics (or new statistics) tutors who need to provide statistics support. They cover key topics including hypothesis testing and choosing the right test. These slides were developed and contributed to the statstutor Community Project by Alun Owen (University of Worcester) and Ellen Marshall (University of Sheffield) and reviewed by Ruth Fairclough (University of Wolverhampton).
