Question: Are urban students more successful? North Carolina State University looked at the factors that affect the success of students in a requited chemical engineering course. Students must get a C or better in the course in order to continue as chemical engineering majors, so a "success" is a grade of C or better. There were 65 students from urban or suburban backgrounds, and 52 of these students succeeded. Another 55 students were from rural or small-town backgrounds; 30 of these students succeeded in the course. Is there good evidence that the proportion of students who succeed is different for urban/suburban versus rural/small-town backgrounds?
