You can see the project network below. After detailed analysis of the project, you found

the expected activity times $($in days$)$ for all ten activities. These numbers are

incorporated into the project network.

Use the given information to answer to the following questions.

$($a$)$ Fill in the activity nodes.

$($b$)$ The critical path is $E-$H$.$H$.$J$],.$ If you get more than one critical path,

please select the upper one. For example, if you have A$-$C$-$G$-$J and B$-$H$-$I$-$J$,$ then you

have to select $A-C-G-J.$

$($c$)$ The expected optimal completion time is $E(t)=$

days.

$($d$)$ Based on the results for the questions $($a$)-($b$),$ answer the following questions:

How many days the activity A can be delayed without increasing the expected

project completion time?

Is it possible that the activity $J$ is delayed without increasing the expected project

completion time? Select an answor $vv$

$($e$)$ The following table shows the calculated expected variance for each activity.
