There is some evidence that students who use Facebook while studying tend to have lower grades than non-users. A representative study surveyed students to determine the amount of Facebook use during the time they study or do homework. Based on the amount of time spent on Facebook, students were classified into three groups and their scores on a 10-point test were recorded. The following data show the results:
