answer this with calculations

Question 5 [25 marks] Assume that operations on a work package were expected to cost 6,500. After 4 weeks they were scheduled to have cost 1,900 but instead have cost 1,500 and it is estimated that S% of the work package has been completed. (S is the sum of the digits in your student number. For example, if your number is 333333, then S = 3+3+3+3+3+3 = 18 and the project progress is 18%.) a) Assume that the project costs are evenly spread throughout the duration of the work package, make a rough sketch of typical cost versus time curves for the Planned Value (PV), Actual Cost (AC) and Earned Value (EV). [4 Marks] b) Calculate the: i. Cost Variance (CV) ii. Schedule Variance (SV) ili Cost Performance Index (CPI) iv. Schedule Performance Index (SPI) Estimated cost at completion (EAC) vi. Estimated cost to complete (ETC) I [3 marks] [3 Marks] [3 Marks] [3 Marks] [3 Marks] [3 marks] 5.
