Required information The Hard Rock Mining Company is developing cost formulas for management planning and decision-making purposes. The company's cost analyst has concluded that utilities cost is a mixed cost, and he is attempting to find a base that correlates with the cost. The controller has suggested that tons mined might be a good base to use in developing a cost formula. The production superintendent disagrees; she thinks that direct labor-hours would be a better base. The cost analyst has decided to try both bases and has assembled the following information: Utilities Cost Direct Quarter Year 1: Tons Mined Labor-Hours First 17,000 5,200 $ 52,000 Second 13,000 3,200 $ 47,000 Third 22,000 4,200 $ 62,000 Fourth 14,000 6,200 $ 77,000 Year 2: First 20,000 10,400 $110,000 Second 27,000 9,600 $115,000 Third 32,000 8,400 Fourth 30,000 11,400 $ 87,000 $124,000 2. Using the least-squares regression method, estimate the variable utilities cost per direct labor-hour and the total fixed utilities cost per quarter. Express these estimates in the form Y=a+bX. (Round the Variable cost to 2 decimal places and Fixed Cost to the nearest whole dollar amount.) Yo
