Cоnsider the fоllоwing scenаrio. A hookworm is аn intestinаl parasite that can infect most vertebrates. If presented with two potential host species, a deer or rabbit, researchers are interested if hookworms have a preference to infect one host species over another. Thus, the null hypothesis states that the probability of hookworms infecting deer and rabbits are the same at prabbit = pdeer = 0.5. In other words, the probability of a hookworm infecting a rabbit or a deer is 0.5. What nonbiological process can be used to build a null distribution, assuming there are only two outcomes [1) hookworms infect deer or 2) hookworms infect rabbits]?
