Two new programs were recently proposed at the University of Florida for treating students who suffer from math anxiety. Program A provides counseling sessions, one session a week for six weeks. Program B supplements the counseling sessions with short quizzes that are designed to improve student confidence. For ten students suffering from math anxiety, five were randomly assigned to each program. Before and after the program, math anxiety was measured by a questionnaire with 20 questions relating to different aspects of taking a math course that could cause anxiety. The study measured, for each student, the drop in the number of items that caused anxiety. The sample values were

Program A: 0, 4, 4, 6, 6

Program B: 6, 12, 12, 14, 16

significance testing in comparing the means of the before and after data for Program A using a 95% confidence level.
