NETWORK: PERT $1-$ Fall $\text{'}24$

Consider the following table:

Construct a PERT network.

$[$NOTE: This is the most crucial part of the exercise. Make sure you have the correct

network before proceeding to the next sections.$]$

By using $t_e$ and ES$,$ EF$,$ LF$,$ LS$,$ state TIMES on the network. Find the slack of each

activity and identify the Critical Path.

Find the average completion time $(\stackrel{}{x}$ Xbar$)$ and $($ Sigma$),$ the standard deviation, for the

project$-$ round off the standard deviation to the nearest hundredth: two decimal places.

What is the completion time at $95\%$ Confidence Interval?

What is the likelihood of this project being completed in more than $14$ days?

Between $15$ and $17$ days?

$($You should provide a Summary and Explanations!$)-$ All work must be clearly shown!

$($Adjust as necessary$)$
