A study conducted in the multicultural Spanish city of Ceuta investigated the relationship between religion and the prevalence of eating disorders. Students aged 12-20 were selected from three public schools. In the study, suppose there were 150 Muslim students and 46 were diagnosed with eating disorders. Of the 200 Christian students, 17% were diagnosed the same way.

Based on your interval, are you convinced that there is a true difference when comparing rates between the religions? Explain.
