ABSTRACT
In previous chapters we have discussed methods for determining the probability of obtaining any particular proportion of events in a sample, given the sample size and the proportion of events in the population. We also discussed methods for determining the probability that two or more randomly drawn, or two correlated sample proportions came from a common population. In each case we defined two or more mutually exclusive categories, counted the observations classified in these categories, and then used tests of significance based on these enumerations.
