A study was conducted to determine if differences in new textbook prices exist between on-campus, off-campus, and Internet bookstores. To control for differences in prices that might exist across disciplines, the study randomly selected 12 textbooks and recorded the price of each of the 12 books at each of the three retailers. Assume normality and equal-variance assumptions have been met. The partially completed ANOVA table based on the study's findings is shown in the accompanying step.
