Question

The report “Undergraduate Students and Credit Cards in 2004” (Nellie Mae, May 2005) included information collected from individuals in a random sample of undergraduate students in the United States. Students were classified according to region of residence and whether or not they have one or more credit cards, resulting in the accompanying two-way table. Carry out a test to determine if there is evidence that region of residence and having a credit card are not independent. Use a = .05.
