Marine biologists want to determine whether a small increase in acidity of sea water would adversely affect marine life.  They randomly assigned several Entacmaea quadricolor (a type of sea anemone), to one of eight aquariums with environments as similar as possible to the natural habitat.  Then they randomly selected four tanks, and gradually increased the acidity of the water.  They monitored the health of the anemones for the duration of the study.  Which is not true about this study?
