Consider the office renovation project data in Table 7.16. A“zero” time estimate means that the activity could take a verysmall amount of time and should be treated as a numericzero in the analysis.a. Based on the critical path, find the probability ofcompleting the office renovation project by 39 days.b. Find the date by which you would be 90 percent sure ofcompleting the project.

The owner of Maxwell's Coffee and Cakes wants to start selling products that feature her coffee shop's logo. Her first product will be backpacks which she will sell for $137.44 each. She can buy the backpacks for $21.97 and have them customized for $10.92 apiece. There is a one-time set up charge of $1,525.15 for customization. In order for the project to go forward, she needs to show a $14,718.68 profit. How many backpacks will she have to sell in order for this project to be acceptable? Round to the nearest whole number.
Dave Fletcher was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined. Here are the activity times: Activity A B с D Time (weeks) 5 8 2 1 Immediate Predecessor(s) A A Dave's earliest start (ES) and earliest finish (EF) are: Activity A Activity EFGH ES Time (weeks) 3 EF 5 5 10 7 Immediate Predecessor(s) B B C, E D, F
Consider a project that has been modeled as in the table below. Part a) Draw the PERT/CPM network for this project and determine the project’s expected completion time μP and its critical path. Part b) Suppose the standard deviations of the activity durations are σA = 2, σB = 1, σC = 0, σD = 2, σE = 3, and σF = 0. Then please estimate the standard deviation of the overall project’s standard deviation σP . Part c) Suppose for the standard Normal random variable Z, we know P[−1 ≤ Z ≤ +1] ' 68%, P[−2 ≤ Z ≤ +2] ' 95%, and P[−3 ≤ Z ≤ +3] ' 99.7%. Then, approximately what time T is one for which there is only a less than 2.5% chance for the completion time to beat (be shorter than)? *Please answer a-c and type your work and answers or write them neatly please* Thank you
A large Southeast city is requesting federal funding for a park-and-ride project. One of the requirements in the request application is a network plan for the design phase of the project.
