A Research and Development team is creating a project plan for developing a new product. Upper management has requested the project be completed in 60 days. They have developed estimated time durations in days for the project as shown in the following table. Activity Immediate Predecessor Activities A Optimistic Time (to) Most Likely Time (tm) Pessimistic Time (tp) 11 13 16 B A 7 11 15 C A 11 16 21 D A 10 10 19 E B 6 7 9 F C, E 11 13 14 G B 13 15 17 H B, D 19 22 25 I B, D ] F, G, H 11 16 21 11 15 Compute the expected time for activity H. 0000 11 19 22 26

There are five activities on a project's critical path and they have standard deviations of 1, 1, 3, 5, 5 days. The standard deviation (in days) of the critical path is: OA. 8.8 OB.9.8 OC.7.8 OD.4.6 O.E. 10.2 OF, 10.6 W F2 A Moving to another question will save this response. #3 20 E F3 D $ 4 DOD 000 F4 R F % 5 F5 T G MacBook Air ^ 6 ....

Given an activity's optimistic, most likely, and pessimistic time estimates of 4, 22, and 28 days respectively, compute the PERT expected activity time for this activity.     7     22     20     none of these     18

Need help with sub question c, d and e.

The following activities are part of a project to be scheduled using CPM: TIME (WEEKS) 7 6 ACTIVITY IMMEDIATE PREDECESSOR A BCDEFG O A-C-D-E-G O A-B-E-G O A-C-D-F-G O A-B-D-F-G AACB A Number of weeks A b. What is the critical path? B, D D E, F 24346 c. How many weeks will it take to complete the project?

. Assume that a project has an expected total duration of 25 days, but several optimistic employees feel that it can be completed in as little as 18 days, while others expect it to take nearly 40 days. Using program evaluation and review technique calculations, what is the project duration to be used in project Gantt charts and other tracking tools?2. If a critical path method calculation of project duration was 25 days, how does the program evaluation and review technique calculation in Question 1 compare?

Using the following project information, calculate the variance for each of the project activities.   Activity   Optimistic TimeEstimate(weeks)   Most Likely TimeEstimates (weeks)   Pessimistic TimeEstimates (weeks)   ImmediatePredecessor(s) A   2   3   5   none B   2.5   4   5   A C   5   7   8   A D   3   5   7   B,C E   4   7   14   B,C F   2   5   8   D G   4   5   6   E H   6   6   8   F I   4   8   10   G J   2   3   3   H,I   (Round your answers to 2 decimal places, e.g. 1.75.)   Activity Variance A enter a variance rounded to 2 decimal places B enter a variance rounded to 2 decimal places C enter a variance rounded to 2 decimal places D enter a variance rounded to 2 decimal places E enter a variance rounded to 2 decimal places F enter a variance rounded to 2 decimal places G enter a variance rounded to 2 decimal places H enter a variance rounded to 2 decimal places I enter a…
