A study was conducted on horses to identify factors that might contribute to the formation of enteroliths-stones that form in the colon of the horse and eventually lead to blockage and death. The table below summarizes disease status, cases that have enteroliths by whether a horse has been altered (geldings have been castrated, mares and stallions have not been altered) and by whether the horse gets the majority of its feed as alfalfa. To study whether being fed alfalfa has any effect on the relationship between case status and having been altered, we should:
A)calculate the conditional probabilities of having been altered for those who are fed alfalfa and for those who are not fed alfalfa.
B)calculate the conditional probabilities of being a case for those fed alfalfa and for those not fed alfalfa.
C)calculate the conditional probabilities of being a case, given being fed alfalfa or not and being altered or not.
D)All of the answer options are correct.
