Identify an appropriate testing method for the difference between population proportions including the parameters.

• The appropriate testing method for the difference between two population proportions is a two-sample z-test for the difference between two population proportions.
• The parameters for a hypothesis test for the difference between two population proportions should reference the population parameters, the response variables, and the populations in context.
