3.24 Blueberries and bones. A study of the effects of blueberries on the bones of mice compared diets containing no blueberries, blueberries as 5% of the diet, and blueberries as 10% of the diet. Ten mice were randomly assigned to each diet. The mice were fed the diets for 30 days, and the total body bone mineral density (TBBMD) was measured at the end of the feeding period. What are the experimental units, the treatments, and the outcomes for this experiment? Would you use the term subjects for the experimental units? Explain your answers.
