Problem 9-09 (Algorithmic) At a local university, the Student Commission on Programming and Entertainment (SCOPE) is preparing to host its first rock concert of the school year. To successfully produce this rock concert, SCOPE has listed the requisite activities and related information in the following table (duration estimates measured in days). Immediate Most Activity Predecessor(s) Optimistic Probable Pessimistic A: Negotiate contract with 10 11 15 selected musicians B: Reserve site 7 9 11 C: Manage travel logistics 5 7 12 for music group D: Screen & hire B 3 4 5 security personnel E: Arrange advertising C 6 6 6 & ticketing F: Hire parking staff A, D 6 8 10 G: Arrange concession sales E 3 9 12 d. What is the expected duration and varience of the critical path? If required, round your answer to two decimals. Expected duration = 33.5 Variance 4.31 e. What is the likelihood that the project will be completed within 30 days? If required, round your answer to four decimals. Note: Use Appendix B to identify the probability Likelihood - 4.6 f. If activity is delayed by six days heyond its carly start time, how does this affert the expected project duration if required, round your answer to one decimal place. A delay of 6 days to activity B will Il affect the time to complete this project because activity B has a slack or 12.5 days. 9. Using all paths through the project network, estimate the probability that the project will be completed within 30 days. Compare your answer to the answer in parte and explain. Round your answers for values to 2 decimal places and for probability values to 4 decimal places.
