    What you’ll learn to do: Recognize when to use a two population proportion hypothesis test to compare two populations/treatment groups.

    LEARNING OBJECTIVES

    • Recognize when to use a hypothesis test or a confidence interval to compare two population proportions or to investigate a treatment effect for a categorical variable.
    • Determine if a study involving two proportions is an experiment or an observational study.
    • Describe the sampling distribution of the difference between two proportions.
    • Draw conclusions about a difference in population proportions from a simulation.
