Problem 21

In an experiment to investigate the effect of cement factor(number of sacks of cement per cubic yard) on flexuralstrength of the resulting concrete (Studies ofFlexural Strength of Concrete. Part 3: Effects ofVariation in Testing Procedure, Proceedings, ASTM,1957: 11271139), I 5 3 different factor values wereused, J 5 5 different batches of cement were selected,and K 5 2 beams were cast from each cement factor/batch combination. Sums of squares includeSSA 5 22,941.80, SSB 5 22,765.53, SSE 5 15,253.50,and SST 5 64,954.70. Construct the ANOVA table.Then,assuming a mixed model with cement factor (A) fixedand batches (B) random, test the three pairs of hypothesesof interest at level .05.22. A study was carried out to
