An experiment employing a randomized block design has 4 treatments and nine blocks, for a total of 4x9=36 observations. Conduct a test at alpha 0.05 to verify whether the block means are equal, knowing that SSTO = 500, SST = 50% of the total Sum of Squares and SSB is = 20% of SSTO. The results of the analysis for block effect are: O F = 2; Rejection region F =2.36 Fail to reject Ho, There is no block effect...
