(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 value, Significance F values and other appropriate criteria to explain your answer.
