The following group means come from Exercise 4 in Chapter 12. Compute the one-way RM ANOVA for these data, assuming that there are a total of 15 blocks of (matched) participants and that SSerror = 5,  40. Is the F ratio significant at the .05 level, based on the unadjusted df (i.e., assuming sphericity)? Would this F ratio be significant at the .05 level, given the worst-case adjustment of the df (i.e., assuming a maximum violation of sphericity)?
