9. 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). a. Draw the project network. b. Compute the expected duration and variance of each activity. c. Determine the critical path in the project network. d. What is the expected duration and variance of the critical path? c. What is the likelihood that the project will be completed within 30 days? f. If activity B is delayed by six days beyond its carly start time, how does this affect the expected project duration? Exercise 13-9 (page 620): Provide the solutions for each of the following: a) Project network - attach your drawing to your assignment. See example, table Figure 13.6 (page 599). b) Expected duration and variance of each activity c) Critical path d) Expected duration Expected duration e) Z value Probability f) 2Page
