Looking at question 1 a-d being completed, I don't know how to do e-h. can you please help?

Question 1 (47 points): Uncertainty of Project Completion Time Given a Project with the following activities and data: Critical Path? Yes No Yes Activity Standard Deviation (0) in weeks i. Add 2 ii. Balance iii. Count 0 iv. Deduct 3 v. Edit vi. Finance 12 vii. Group viii. Hold Expected Time, TE (weeks) 2 3 4 2 1 6 4 2 No Yes No Yes Yes Find the following: a. (10 points). What is the Variance for each Activity on the Critical Path? Please place your answers (for Activities on the Critical Path only) in the worksheet (table) below (in column for Variance). (2 points for correct Variance * 5 Activities on the Critical Path = 10 points) Activity Standard Deviation (0) in weeks 2 1 Expected Time, TE (03) (weeks) 4 12 1 3 04 9 2 i. ii. iii. iv. v. vi. vii. viii. Add Balance Count Deduct Edit Finance Group Hold 2 2 0 4 4 0 6 4 2 b. (2 point) What is the Sum of Variances across all Activities on the Critical Path? Place your answer in the box below (2 points for correct Sum of Variances * 1 Sum of Variances = 2 points) Sum of Variances (0%) in Critical Path Due Tuesday, April 14, 2020 at 6 pm Question 1: Uncertainty of Project Completion Time (continued) c. (2 points) What is the expected Project Duration (u)? Place your answer in the box below Expected Project Duration (u) in Weeks d. (15 points) Using the table on page 5 of this assignment, calculate Expected Project Duration, Sum of Variances in the Critical Path, and Z. Place your answers in the table below and your calculations in the box below. (2 points per "Sum of Variances in Critical Path" * 3 values = 6 points + 2 points per correct "Z" value * 3 "Z" values = 6 points) + 3 points for correct calculations.
