Question Completion Status: 12 points Save an A new project has been defined to contain a list of activities A, B, C, D, E, F, G, & H. Attached is the spreadsheet with the activities and time estimates for each of the activities. Fall 2021 Critical Path Test Question Table.xlsx This problem is worth 12 points: A) 3 points, B) 3 points, C) 1 point, D) 3 points, E) 2 points. A) Calculate the expected times (ET) for each of the activities using the PERT method. B) The project has eight activities: A. B, C, D, E, F G, H, and the expected times were calculated in part a). Thus, parts b)-e) are based on the critical path. The spreadsheet table provides the precedence relationships Given the information provided in the table above and the expected times calculated in part a), what are the various paths from (start to finish) along with the time durations and units? C) What is the critical path along with the time duration? D) What is the slack/float time for activities D. E, and F? E) What would happen if activity D were revised to take 6 weeks instead of the expected time (ET) calculated in part a)? Attach a file with your work which can be typed or handwritten.
