You have become concerned about the amount of copier paper used in your office after repeatedly running out of supplies. Your assistant keeps track of the number of reams (packages of 500 sheets) for 24 weeks:

Week	1	2	3	4	5	6	7	8	9	10	11	12
Reams of paper	232	263	271	248	235	261	207	243	237	293	243	260
Week	13	14	15	16	17	18	19	20	21	22	23	24
Reams of paper	253	270	230	253	238	272	222	243	289	238	262	234
