7. The owner of a regional retailer has noticed an increase in absenteeism among his work force. He believes this is due to a lack of general health in his employees. In an attempt to improve the situation, six months ago he began a fitness program in which employees exercise during their lunch hour. To evaluate the program, he selected a random sample of nine employees who participated in the program and found the number of days each missed work in the 6 months prior to the program and in the 6 months after implementation of the program. The results are summarized in the table below. Construct a 90% confidence interval for the difference in employee absences before and after implementation of the program was implemented. Interpret your interval (i.e. what, exactly, does it mean in this case). Round to 4 (four) quality decimal places.
