2. Complete the least-squares regression equation for the departments costs. (Do not round intermediate calculations. Round variable cost per unit to 2 decimal places and other answer to the nearest whole dollar amount.) 3. Predict the firms material-handling departments costs for a month when 2,350 units of activity are recorded. (Do not round intermediate calculations. Round variable cost per unit to 2 decimal places and final answer to the nearest whole dollar amount.)
