Enteroliths are calcifications that form in the gut of horses. The stones can cause considerable morbidity and mortality. A study was conducted to investigate factors (such as age, diet, and environment) that may be related to the formation of enteroliths. The researchers decided to draw two histograms: one for horses with enteroliths (cases) and one for horses without (controls). The number of horses 20 years and older:
A)is larger among the cases.
B)is smaller among the cases.
C)is about the same for both.
D)cannot be determined from the histogram.
