WalMart’s fiscal year starts the first week of February. This means that when analyzing the data, week 26 is actually week 30 (26+4 weeks for January) in 2002 or the end of July 2002. Also, week 52 is actually week 4 (52+4 weeks for January 2002 minus 52 weeks for 2002) in 2003 or the end of January 2003. As an example, the spike in sales (revenue) at week 75 occurs in week 27 (75+4 weeks for January 2002 minus 52 weeks for 2002) in 2003 or the first week in July 2003. This corresponds to sales for the July 4th holiday when people are buying barbecue related items.

I want to know how to solve the following in excel. What is the x value and what is the Y value using the data table below?
Wal-Mart is the second largest retailer in the world. The data file (Wal-Mart Revenue 2004-2009.xlsx) is posted below the case study one file, and it holds monthly data on Wal-Mart’s revenue, along with several possibly related economic variables.
A. Develop a linear regression model to predict Wal-Mart revenue, using CPI as the only independent variable.
B. Develop a linear regression model to predict Wal-Mart revenue, using Personal Consumption as the only independent variable.
C. Develop a linear regression model to predict Wal-Mart revenue, using Retail Sales Index as the only independent variable.
D. Which of these three models is the best? Use R-square values, Significance F values, p-values and other appropriate criteria to explain your answer.
E. Generate a scatter plot, residual plot and normal probability plot for the best model in part (d) and comment on what you see.
