Using the accompanying computer output based on the data in Problem 7 in Chapter 17, conduct a randomized-blocks analysis, treating the high schools as blocks, to test whether significant differences exist among the average math SAT (MSAT) scores for the years 2002, 2007, and 2012. Do the results obtained from this randomized-blocks analysis differ from those obtained earlier from the one-way ANOVA?
