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 by sex (gelding, mare, and stallion). If you want to check whether there is an association between sex and case status, you should:
A)compare the conditional probabilities of being a case, given sex.
B)make a scatterplot of case status versus sex.
C)compare the marginal probability for case status and sex.
D)All of the answer options are correct.

To determine whether there is an association between sex and case status, we need to compare the conditional probabilities of being a case given the sex of the horse. This helps us understand whether there is a higher or lower probability of being a case based on the sex of the horse. Making a scatterplot or comparing marginal probabilities would not provide us with this information. Therefore, the best choice is A.
