A finance executive would like to determine if a relationship exists between the current earnings per share (EPS) of a bank and the following independent variables:
• Total assets ($ billions)
• Previous period’s EPS
• Previous period’s return on average assets (ROAA)
• Previous period’s return on average equity (ROAE)
ROAA measures how effectively assets are utilized, and ROAE measures a firm’s profitability. The Excel file Bank EPS. xlsx contains these data for several banks.

d. Identify the regression equation for the model in part c.
e. Perform a residual analysis with the model in part c to verify that the conditions for the model are met.
