A manufacturer of infant formula is running an experiment using the standard (control) formula, and two new formulas, A and B. The goal is to boost the immune system in infants. One hundred twenty infants in the study are randomly assigned, to each of three groups: group A, group B, and a control group. The study is run for 12 weeks. At the end of the study the variable measured is total IGA (in mg per dl), with higher values being more desirable. We are going to run a one-way ANOVA on this data. A partial ANOVA table is given below.
