1. Students in LEAD 5700 took a pre-test of their statistics knowledge, and a final exam testing their statistics knowledge. The professor hypothesizes that the students' pre-test scores will be positively related to their final exam scores. Is this hypothesis accurate? Use the students' pre-test scores (PreScore) and the students' final exam scores (FinalScore) to compute a Pearson R correlation to determine the validity of this hypothesis.
a. What is the professor's research question?
b. Is this hypothesis accurate? How can you tell?
c. Create a scatterplot of the correlation between PreScore and FinalScore.
