Assume the time used for each activity is the expected time required to finish that activity,

and the project completion time calculated in part $4$ is the expected completion time for the

project and also project variance is $10$ weeks. What is the probability of finishing the

project within a range of $3$ weeks earlier than the expected completion time and $1$ week

later? Additionally, what is the probability of finishing the project $4$ or more weeks beyond

the expected completion time? Lastly, what due date would yield a $75\%$ chance of

completion?

$9.$ Suppose that project indirect costs are $$7,000$ per week. Suppose also that, after week $25,$

a penalty cost of $$22,000$ per week if the project is not fully completed. For every week

that the project is shortened$$to week $25$the Hard Rock Cafe saves one week of penalty

and indirect costs. For reductions beyond week $25,$ the savings are only the weekly indirect

costs. Determine the minimum$-$cost schedule for the Rockfest concert project. The goal

here is to determine how much you can add in crash costs without exceeding the savings

in indirect and penalty costs. In accordance with Hard Rock Cafe's standard procedures,

you are required to create an executive summary aimed at your project manager. The

purpose of this summary is to persuasively present your recommendations from question

$6$ and convince the manager to consider them $($you can use graph to support your

recommendations$).$ The document must be of professional quality in both content and

format and must clearly outline each step taken in determining the minimum$-$cost schedule.
