Profitability remains a challenge for banks and thrifts with less than $2 billion of assets. The businessproblem facing a bank analyst relates to the factors that affect return on assets (ROA), an indicator ofhow profitable a company is relative to its total assets.Data collected from a sample of 20 community banks include the ROA (%), the efficiency ratio (%), asa measure of bank productivity (the lower the efficiency ratio, the better), and total risk-based capital(%), as a measure of capital adequacy.a. State the multiple regression equation.Let X1i represent the efficiency ratio (%) and let X2i represent the total risk-based capital (%).(Round the constant to two decimal places as needed. Round the coefficients to four decimal placesas needed.)b. Interpret the meaning of the slopes, b1 and b2, in this problem
