please solve e and f . or the whole question.

thank you

QUESTION 1: Using the information from the following table a) Assume the organization you work for computes TE based on the standard beta distribution formula, calculate the expected activity times (round to nearest integer). b) Using the AON technique, construct the network, calculate the activity slacks, ES, EF, LS and LF. Make sure you fully label all nodes in the network. c) Identify the critical path. What is the total project duration? d) Given the activity variances, what is the likelihood of the project finishing on day 84? e) Suppose you wanted to have a 99% confidence in the project finishing on time. How many additional days would your project team need to negotiate for in order to gain this 99% likelihood? f) Now, assume that activity E has taken 10 days past its anticipated duration to complete. What happens to the project's schedule? Is there a new critical path? Activity Preceding activities Best Likely Worst TE A 12 15 25 B A 4 6 11 12 12 30 D B, C 8 15 20 E A 7 12 15 0 W .
