At Hinsdale College, students are employed by the college library to re-shelve books. The students claim that a 15-minute coffee break every hour would relive boredom and increase the average number of books re-shelved per hour. To test the student's claim, the following data were gathered on a random sample of seven student employees. Over a period of one week, each student worked a normal schedule without coffee breaks. Then, during the next week, the students were allowed coffee breaks. Unknown to the students, a member of the library staff secretly recorded the average number of books shelved per hour and computed the averages with and without the coffee break system. The results are below. Test the claim that the students shelve more books when they have a coffee break, use a 0.05 level of significance.
