An experiment was conducted to compare the use of iPads versus regular textbooks in teaching algebra to two classes of middle school students.† 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.
iPad Textbook
Mean 86.8 79.5
Standard Deviation 8.97 10.8
Sample Size 10 10
Required:
a. use the summary data to test for a significant difference in advancement scores for the two groups using α= 0.05.
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?
