Question 1 The following activities are required by the promoter of a gospel concert. They can be viewed as a mini-project and are summarized in the following table: Table 1: Activity Times and Predecessor's Activity Predecessors Optimistic Most likely Pessimistic time (a) time (m) time (b) 2 4 7 A 6 10 A 3 B AWAN B B. C B 1 F 2 3 F, H I AN- K D, E 10 You must use two decimal places where activity times and variances are fractional. Failure to do so is a violation of instructions (and can result in the wrong answer). Required a. Draw the activity network for this problem (either AON or AOA). b. Determine the expected time and variance for each activity. C. Show the activity schedule (ES, EF, LS, LF) as well as the slack. You may work in the network or show the results in a table. d. Determine and state the critical path for this project. This must be based on your work in c) and not by inspection. e. What is the expected time, variance and standard deviation of the project? Wh
