A student group is conducting a study to determine whether there is a difference between textbook prices for new textbooks sold by on-campus bookstore at a university and an Internet retailer. A random sample of 10 textbooks was taken and the campus price and the Internet retailer's price for each text book were collected. At the 0.01 level of significance, can the student group conclude that there is a difference in average textbook prices for new textbooks sold on campus and over the Internet?
