Please show the process to get each other. I need to know how you get t, ES, EF, LS, and LF. How do you know what the critical path(s) is?

(4) Perform a project management analysis for the data given below to determine ES, EF, LS, LF, and slack for each activity, the total project completion time, and the critical path. Activity Time (weeks) Predecessors Activity Time (weeks) Predecessors 7 5 7 A CE 3 A DF (a) Draw a network with , ES, EF, LS, and LF (follow the same format as Figure 12.5 on page 468). A B 6 4 E F G B B D 11 8 EF LE Slack Critical? (b) Complete the following table (similar in formar to Table 12.3). Activity Time (weeks) ES LS B D E F G H (c) Identify the critical path(s): (d) Based on your analysis, the project completion time is: weeks and the least critical activity is
