You want to examine competition in barnacles. You examine two species and count the number of each species at the low and high water marks (many barnacles live in tidal areas). You get the following results: Low water 59 21 High water Species A Species B 19 45 (a) Is there a difference between species depending on high and low water (is water level independent of species)? (b) Which species prefers low water? Which prefers high water (you need to calculate some proportions to answer this question)?
