#4: Problem 3.17 (p 96) in the book, but do only these questions. (30 points, it's rather long) (a) Calculate the Expected Time and Variance for all activities (You don't have to show this work, you can use a spreadsheet or calculator. Just write it down on the sheet). Please keep two significant digits (Example: Activity A should be 7.67 weeks). (b) On the next page after this, draw the full network (Activity on Node style), and calculate using the Expected Time what the Critical Path is (just use the CPM method we did last week with Earliest Start, Earliest Finish, etc.) (c) Calculate the Activity Variance for the Critical Path, then calculate the Standard Deviation for the Critical
