Question

Augmented Reality (AR) is a technology that superimposes a computer-generated image on a user's view of the real world, and it is believed that it will soon affect the conventional learning process. A random sample of nine university students was selected to test for the effectiveness of a special course on augmented reality in learning. They were taught how to incorporate AR into their learning process to its full potential. Table 1 gives the scores in a Learning Effectiveness test given to these students before and after attending this course.

Construct a 95% confidence interval for the mean (mean difference) of the population paired differences.

Table 1: Scores of a Learning Effectiveness test before and after attending the AR course.
