Doctors report incidences of illness, such as influenza, to the Centers for Disease Control (CDC). The graph below shows data for three years. Note that this graph shows from October of one year to October of the following year. The leftmost data on the graph begins with week 40 (October) and shows data through the end of the year. The tick mark for week 1 (beginning of January) is roughly in the middle of the x axis. One journal said that influenza trends in 2008-09 were unusual. Based on the evidence in the graph, what range of data did the journal most likely use to support the claim? week 1 through week 13 week 13 through week 15 week 16 through week 24 week 40 through week 46
