12. Books or iPads? An experiment was conducted to compare the use of iPads versus regular textbooks in teaching algebra to two classes of middle school students.

6 To remove teacher-to-teacher variation, the same teacher taught both classes, and all teaching materials were provided by the same author and publisher.

Suppose that after 1 month, 10 students were selected from each class and their scores on an algebra advancement test recorded. The summarized data follow.

a. Use the summary data to test for a significant difference in advancement scores for the two groups using a 5.05.

b. Find a 95% confidence interval for the difference in mean scores for the two groups.

c. In light of parts a and

b, what can we say about using iPads versus traditional textbooks in teaching algebra at the middle school level?
