Abstract: Abstract In the last Chapter we focused on estimating and conducting a hypothesis test on a proportion from a single group. In practice, we are often interested in comparing proportions from two separate groups, and as such we would perform a hypothesis test comparing the proportions from those two different samples. The process for the two-sample case is similar to that for the one-sample case, in that we will go through the same general steps, though the details of those steps will be different. Further, there are additional statistical techniques that we perform, depending upon the status of our assumptions.
