The report, “Undergraduate Students and Credit Cards in 2004: An Analysis of Usage Rates and Trends” describes the results of a survey of college students. Based on the data collected, the report concluded 5 that about 21% of undergraduates with credit cards pay them off each month. The report also concluded that the average outstanding balance on undergraduates’ credit cards is about $2,169. The survey data was from an online survey that was emailed to 1,260 students. Responses were received from 132 of these students. What concerns do you have about generalizing these conclusions to the population of all undergraduate students?
