She convinces professors who teach business and nursing courses to distribute a short anonymous survey in their classes. The question about cheating is one of many other questions about college life. From this data, the student plans to calculate a confidence interval for the difference in two population proportions. Which is the most reasonable description of the two populations for her conclusion? business and nursing students in the classes that were surveyed business and nursing students at DVC business and nursing students at community colleges business and nursing students at community colleges the year of the study
