Here is a question and answer. I need the answer for e)PROBLEM 5 (8 points)DayACPVEV65$550$735$678a) Calculate the cost variance (CV). (2 points)-550 The Cost Variance of the project is $128b) Calculate the cost performance index (CPI). (2 points)The CPI of the project is EV/AC = 678/550 = 1.23c) Calculate the schedule variance (SV). (2 points)The schedule variance of the project is EV-PV -735 = -$57d) Calculate the schedule performance index (SPI). (2 points)The SPI of the project is 678/735 = 0.92e) Given these data, what should a project manager do with respect to this project?
