Please solve , most important part e, Thank you

Given the following information for a one-year project, answer the

following questions. Assume you have actual and earned value data

at the end of the second month. Recall that PV is the planned value,

EV is the earned value, AC is the actual cost, and BAC is the budget

at completion.

PV = $23,000

EV = $20,000

AC = $25,000

BAC = $120,000

a. What is the cost variance, schedule variance, cost performance

index (CPI), and schedule performance index (SPI) for the

project?

b. How is the project progressing? Is it ahead of schedule or behind

schedule? Is it under budget or over budget?

c. Use the CPI to calculate the estimate at completion (EAC) for

this project.

d. Use the SPI to estimate how long it will take to finish this

project.

e. Sketch the earned value chart for this project, using Figure 8-4 as

a guide. Assume the data for month 1 is half of the values given

for PV, EV, and AC at the end of month 2.
