Let X1i represent the efficiency ratio (\%) and let X2i represent the total risk-based capital (\%). y^i=+x1i+(x2i (Round the constant to two decimal places as needed. Round the coefficients to four decimal places as needed.) b. Interpret the meaning of the slopes, b1 and b2, in this problem. Choose the correct answer below. A. For each increase of 1% in both the Efficiency Ratio and the Risk-Based Capital, the ROA is estimated to increase by (b +b2)%. C. For each increase of 1% in the ROA, the Efficiency Ratio is estimated to increase by b1% and the Risk-Based Capital is estimated to increase by b2%. D. The slopes, b1 and b2, cannot be interpreted individually. c. Predict the mean ROA when the efficiency ratio is 60% and the total risk-based capital is 25%
