A randomized block design has four levels of factor A and three levels of factor B. Five replicates for each combination are examined. The results include the following sum of square terms:
SST = 2500 SSA = 1200 SSB = 1000 SSE = 280
a. Construct an ANOVA table
b. At the 5% significance level, can you conclude that there is interaction between factor A and factor B?
c. At the 5% significance level, can you conclude that the factor A means differ?
d. At the 5% significance level, can you conclude that the factor B means differ?
