Need help all three graphs answers options are : average cycle time , boards completed, and direct labor hours

Richard Ellis, the director of cost operations of Northeast Devices, wishes to develop an accurate cost function to explain and predict support costs in the company's printed circuit board assembly operation Requirements 1. Match each graph to the applicable cost driver. 2. Use regression analysis to measure cost functions using each of the cost drivers. 3. According to the criteria of plausibility and reliability, which is the best cost driver for support costs in the circuit board assembly department? 4. Interpret the economic meaning of the best cost function. (Click the icon to view additional information.) E: (Click the icon to view support costs and cost driver data.) Requirement 1.

Match each graph Mr. Ellis is concerned that the cost function that he currently uses-based on direct labor costs-is not accurate enough for proper planning and control of support costs. Mr. Ellis directed one of his financial analysts to obtain a random sample of 25 weeks of support costs and three possible cost drivers in the circuit-board assembly department: direct labor hours, number of boards assembled, and average cycle time of boards assembled. (Average cycle time is the average time between start and certified completion-after quality testing-of boards assembled during a week.) Much of the effort in this assembly operation is devoted to testing for quality and reworking defective boards, all of which increase the average cycle time in any period. Therefore, Mr. Ellis believes that average cycle time will be the best support cost driver. Mr. Ellis wants his analyst to use regression analysis to demonstrate which cost driver best explains support costs.
