9-4 Instructions:Construct a labeled, network model from the information in the following table and identify all the paths in the network, compute the length of each path, and indicate the critical path.

9-5 Instructions: For the network in Problem 9-4, determine the earliest start and finish times (ES, EF), latest start and finish times (LS, LF), and Slack for each activity. Indicate how the critical path would be determined from this information. These results will be in a table format with formulas, however you can calculate by hand first to check your answers.

Table:

Activity	Activity Predeccesor	Time (Weeks)
1	---------	7
2	---------	10
3	1	6
4	2	5
5	2	4
6	3, 4	3
7	5, 6	2

All answers must be displayed in a Word file for responses and an Excel file for calculations
