Problem 9-12 (Algorithmic) Assume that the activity time estimates (in days) for the swimming pool construction project are as follows: Start Activity Optimistic Most Probable Pessimistic Earliest Latest Earliest Latest Critical Activity Start Start Finish Finish Slack Activity 0 1 > No X Yes 8.5 Yes > X X X No No X DIIIIIIII X X X Yes X X No X X Yes X Yes Critical Path: B-C-F-H-I 2. What is the expected time to complete the project? If necessary, round your answer to two decimal places. (T) = 13.67 x days c. Based only on critical path, what is the estimated probability that the project can be completed in 25 or fewer days? Variance = . If necessary, round your answers to two decimal places. Using the normal distribution, z = If necessary, round your answers to two decimal places. If negative answer is required, enter the minus sign before the number. Probability of 25 days or less is . If necessary, round your answers to four decimal places. Note: Use Appendix B to identify the probability
