b$.$ Identify all the paths through the network and their lengths. Fill in the table below $($enter your responses as whole numbers$)$

a$.$ Choose the correct network dagram below.

c$.$ The critical activities are

$,$ so they make up the critical path.

The entire project will take days to complete. $($Enter your response as a whole number.$)$

d$.$ After you completed part b and before you performed the forward and backward passes, you could already tell that activities A and N are on the critical path$($s$).$ Why?

A$.$ Activity N has only two predecessors.B$.$ They are always the start and end activities.C$.$ Delay in these activities will not cause the entire project to be late.D$.$ The durations of these activities are the largest.

e$.$ After constructing the project network diagram, management comes up with the following information regarding how many days certain activities can be crashed and at what cost. Suppose that every day the project goes on costs the company $\backslash (\backslash$$ $7,000\backslash ).$ How many days should management crash the project? What activities should it crash? What is the new project length?Click the icon to view the number of days certain activities can be crashed and its cost.

Management should crash activities $\backslash (\backslash$square $\backslash )$ day$($s$)$ and day$($s$).($Enter your responses as whole numbers.$)$
