Consider a two-way analysis of variance with one observation per cell and randomized blocks with the following results:



Source of Variation       Sum of Squares     Degrees of Freedom

Between groups                      131                             3
Between blocks                       287                             6
Error                                        360                            18
Total                                        778                            27


Compute the mean squares and test the hypotheses that between-group means are equal and between- block means are equal.
