A Reading Specialist Would Like to Know Whether the Page $\alpha$

Essay

A reading specialist would like to know whether the page layout has any consistent effect on children's reading speed. He printed the same story in three types of page layout (one-column, two-column, and three-column), and then randomly assigned 15 children to each group. The time each child took to finish reading is recorded and compared using the one-factor ANOVA model. Complete the following ANOVA summary table using $\alpha$ = .05. Based on the results, does page layout have an effect on the speed of reading?
