Enteroliths are calcifications that form in the gut of a horse. The stones can cause considerable morbidity and mortality. A study was conducted to investigate factors such as diet and environment that may be related to the formation of enteroliths. The study contained 62 horses with enteroliths (cases, the left graph) and 75 horses without (controls, the right graph). The graph below contains side-by-side boxplots of ages for cases and controls. Which of the following is true about these groups. Box plot of age by diagnosis 30 25 20 15 10 case control
