Scenario
A researcher is interested in examining whether or not standardized testing scores are biased
against students that are English as a second language (ESL) when compared to native English
speakers (EFL). To answer their research questions, they survey senior-level college students,
chosen randomly via a random number generator, and ask them about their HSGPA, the
cumulative college GPA, and their ESL status. Use the data in the following two scenarios to
answer the researcher's questions.
