A professor in the school of business wants to investigate the prices of new textbooks in the campus bookstore and the competing off-campus store, which is a branch of a national chain.

The professor randomly chooses the required texts for 12 business school courses and compares them prices in the two stores. The results are as follows:

Book Campus Store ($) Off-Campus Store ($)

1 55.00 50.95

2 47.50 45.75

3 50.50 50.95

4 38.95 38.50

5 58.70 56.25

6 49.90 45.95

7 39.95 40.25

8 41.50 39.95

At the .01 significance, is there any evidence of a difference in the average price of business textbooks between the two stores?
