This can be discerned in the graph, or by examining the sales figures for most months. c) There is a seasonal factor, with sales high in the summer and winter. Increase in summer is expected since consumption increases with heat and vacations, but the winter must be because of the 2 major hollidays. d) There is definitely an anomaly in October of '96, which changed from the month with the lowest sales in 1994 to the highest in 1996.
