One-tailed tests; Two-tailed tests

8 SUMS AND DIFFERENCES OF DISTRIBUTIONS
Uniform and triangular distributions
Combining different uniform distributions
The difference of two distributions; C T: an exception
Combining multiples of distributions; Does T T T always equal 3T? Bernoulli trials; Mean of the binomial distribution
Variance of the Bernoulli distribution; The general Bernoulli distribution; Relating binomial and Bernoulli variables

9 THE POISSON DISTRIBUTION
Modelling random events; A model for P(O) evaluating the model; Recurrence formula; Probability function the value of the factor; Probability distribution; Poisson probability distribution; Using the Poisson distribution; Validating the model; The distribution function; Mean and variance
Additive property of Poisson variates; Hypothesis tests
