Three loaves of bread, each made according to a different recipe, are baked in one oven at the same time. Because of possible uncontrolled variations in oven performance, each baking is treated as a block. This procedure is repeated five times, and the following measurements of density are obtained.

(a) How should the three oven positions of the three loaves be selected for each trial?
(b) Perform an analysis of variance for these data.
