Use RStudio. To test if a middle school class on geography is
working, a pre- and post-test were given to students at the start
and end of the semester. Assume that the scores were randomly
selected from the two tests. Also, assume that that they are pairs
of scores for ten students. Use the following data to test if the
class improved students’ knowledge of geography. (hint: use
“var.equal=TRUE” in your argument)
Scores
Pre-test: 77, 56, 64, 60, 57,...
