A new teaching method for a math class is being evaluated. A set of 80 students is formed into 40 pairs, where the two-pair members have roughly equal mathematics test scores. The pair are then randomly split, with one member being assigned to section A where the standard teaching method is used and with one member being assigned to section B where the new teaching method is tried. At the end of the course all the students take the same exam and their scores are shown in the TXT file on BlackBoard. Analyze the data and present your conclusions regarding how the new teaching method compares with the standard approach. (Use Paired Sample t-test) The data set is in the proj1-3.txt file on BlackBoard.
