Consider the office renovation project data in the following table. A "zero" time estimate means that the activity could take a very small amount of time and should be treated as a numeric zero in the analysis. a. Based on the critical path, find the probability of completing the office renovation project by 39 days. Refer to the standard normal table (Make sure to round all intermediate calculations for te and variance to two decimal places.) The probability is
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

Following are the three time estimates for a task in a project: optimistic completion time = 2 weeks most likely completion time = 4 weeks pessimistic completion time = 7 weeks Compute the expected time for the task.
Answer all. What are the critical activities? What is the expected project duration? calculate the variance of the project What is the standard deviation (te) for the project? Suppose that management allotted 13-unit time for the project. What is the probability that we will meet the 13-unit time deadline? If management wants to have a 0.99 probability of meeting the time, what should be the scheduled project duration?
2. A small software development project at Krishna Dhir's firm has five major activities. The times (in days) are estimated and provided in the table below: Activity Immediate Predecessor a m b A − 2 5 8 B − 3 6 9 C A 4 7 10 D B 2 5 14 E C 3 3 3 Part 2 d) The probability that it will take more than 17 days to complete this projectbe is __ (keep two decimal places). e) The due date that yields a 98% chance of completion is ____ days (keep two decimal places).
A project consists of seven activities, lettered A through F below. For each activity, the estimated normal time in number of weeks, crash time, normal cost, crash cost, and its preceding activity are given.
