1. Compute the least-squares regression estimate of the variable- and fixed-cost components in the companys material-handling department costs. (Do not round intermediate calculations. Round "Variable-cost component" to 2 decimal places and other answer to the nearest whole dollar amount.)

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 2,050 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.)
