Imagine that our college is having financial problems. The college announces that it will shorten library hours to save money. The library will be closed nights and weekends. Some students that it is okay to pay $20 fee to the college to keep the library open nights and weekends. We are interested in learning about the proportion of students who would pay a $20 fee to keep the library open nights and weekends. To investigate this question, we select a sample of 100 students. We ask each of the students whether he or she agrees with the $20 fee increase to keep the library open nights and weekends. A) Does this study ask a question about a population or about a cause and effect relationship between two variables?
