1. Noah wants to better understand monthly cash flows. To do this, he wants to know the monthly pattern of expenses for gross wages in 2015 (monthly wages are not available for 2016). That is, prepare a query that shows each month (sorted so January is listed first) and how much the amount of gross wages for that month differs from the average of the gross wages for the first six months. Positive values should show that the average for that month was more than the overall average. Using a formula, round your answers to two decimal places. Which month or months should Noah plan to have extra cash for higher-than-normal wage expenses?
