Question
![Scenario 3
Suppose a professor is interested in seeing whether or not gum can be used as a successful retrieval cue for
course material. To test their hypothesis, they randomly assign sections of their statistics class to receive gum or
receive nothing during their review sessions and subsequently during their exam. They randomly select a subset
of students scores from each section. Use the data on the next page to help calculate the appropriate t-statistic
for the research question and engage in hypothesis testing to determine if the professor's hypothesis was
supported.
