Two methods of memorizing difficult material are being tested to determine if one produces better retention. Nine pairs of students are included in the study. The students in each pair are matched according to I.Q. and academic background and then are assigned to the two methods at random. A memorization test is given to all the students, and the scores below are obtained. Is there is a significant difference in effectiveness of the two methods. Use RStudio to perform a repeated-sample t-test with α = .05. Print your computed t-statistic, your critical t-value, and explain your conclusion.
