C 3.41 (3.41) 0.007384Q (2.84) 0.000005359Q2 (3.16) 23.0X1 (3.23) where C = average operating expense ratio, expressed as a percentage and defined as total operating expense ($ million) divided by total assets ($ million) times 100 percent. Q = output; measured by total assets ($ million) X₁ = ratio of the number of branches to total assets ($ million) Note: The number in parentheses below each coefficient is its respective t-statistic. Holding constant the effects of bank branching (X1), what is the level of total assets that minimizes the average operating expense ratio? $1,557.42 million O $688.93 million $461.81 million $1,377.87 million What is the average operating expense ratio for a savings and loan association with the level of total assets determined in the previous part and 1 branch? 1.18% 0.90% 4.94% 3.44% What is the ratio with 10 branches instead? 1.20% ○ 1.48% O 3.74% 5.24%
