Your answers will be wrong since you are working with a different set of numbers. If you procure old assignments from students or websites and use the data for your assignment, you will receive a zero because it is considered an egregious violation of the University's academic integrity policy. The case will be referred to the Office of Academic Affairs and become part of your collegiate record. In certain circumstances, you may be awarded an F for the course.
