An information on a project contains in a table below, each activity is labeled with A to K along with other information time in week.

1) Complete information in the tables columns for the project Expected Time & Variance. (5 markah/marks)

2) Determine the time of the project can be completed and critical path. (2 markah/marks)

3) Complete the table and slack for the project. (2 markah/mark)

4) Construct a figure of AON node configuration network based on answer 1. (9 markah/marks)

5) What is the probability that the project will be completed two weeks before its expected completion date with an illustration? (4 markah/marks)

6) Complete the spaces in Normal Time and Crash Cost Per Week. (4 markah/marks)

7) Calculate the total new project cost and the crashing cost if the completion time can be reduced by six weeks based on information in the table at question six (6).
