you decide to estimate duration and standard deviation of a project using PERT method. the project has 3 steps the following are the optimistic, most likely and pessimistic durations in weeks:step 1: 2,5,10Step 2: 1,3,13Step3: 7,8,11,what is the estimated duration and standard deviation of the project duration?Estimated Duration =16 standard Deviation =4.9Estimated Duration =18 standard Deviation =4.9Estimated Duration =18 standard Deviation =2.49Estimated Duration =16 standard Deviation =24

Use the following information to answer the questions that follow. Some of your project’s activities are listed below, with time estimates given in days. Activities A and N have been identified as critical. Activity Optimistic Most Likely Pessimistic A 4 6 12 B 2 3 3 D 1 2 3 F 1 2 4 N 2 5 8 What is the standard deviation of the project completion time? 1.67 1.78 2.78 3.17

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.

Jordanne King, the project manager for Webjets International, Inc., compiled a table showing time estimates for each of the activities of a project to upgrade the company’s Web page, including optimistic, most likely, and pessimistic.a. Calculate the expected time, te, for each activity.b. Calculate the variance, s2, for each activity.Activity         Optimistic (days)      Most Likely (days)     Pessimistic (days)A                        3                                  8                            19B                         12                              15                            18C                        2                                 6                              16D                         4                                 9                            20E                         1                                   4                               7

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

The following information relates to a project (task times are in weeks).
