Veterinarians Suspect That Enteroliths (Calcifications in the Gut of Horses)

Multiple Choice

Veterinarians suspect that enteroliths (calcifications in the gut of horses) are related to diet-in particular, alfalfa. To investigate this suspicion, a group of veterinarians collected information on the diet of horses and whether the horses developed enteroliths. The table below displays the findings (a case is a horse with enteroliths, a control is without enteroliths) . There is a relationship between being fed alfalfa and having enteroliths because:

A) P(enteroliths | > 50% alfalfa) > P(enteroliths | 25%-50% alfalfa) > P(enteroliths | < 25% alfalfa) .
B) fewer horses get more than 50% alfalfa.
C) the proportion of horses that have enteroliths and eat more than 50% alfalfa is the largest probability in the "Case" row of the table.
D) None of the answer options is correct.
