In the space provided below create the network diagram that shows the relationship (logic) of project activities shown below and then number each event. 1. In a given project activities "A, B and C are initial activities that may begin at the same time 2. -----"D" cannot begin until "A" is complete. 3. ----- "B" must be complete before E can begin. 4. ----- "F" cannot start until "C" is finished. 5. ----- "G" cannot begin until "B" is finished. 6. ----- "G" and "D" must be done before "H" can begin. 7. ----- "I" cannot begin until "B" is finished. 8. ----- "J" can begin only after "F" and "I" are complete. 9. ----- Once "E" is complete, "K" can begin. 10. ---- The project will be finished when "H" "J" and "K" are complete.
(i) Project's standard deviation is the square root of the variance. Write a formula in cell F48 to compute the project's standard deviation.(j)The earliest finish time for the last activity is the Project's duration. Write a formula in cell F50 to compute the project's duration. (Hint: You have to only refer to the cell range)We would like to use the variance information to compute the probability that the entire project will be complete in 35 days.

Please do not give solution in image formate thanku. There are four critical paths in a network. A-B-C-D-E, A-F-E, A-B-H-J-K-E and A-S-T-E. Each activity in this network can be crashed by a maximum of 4 weeks. The crashing cost (per week), for the first week (crashing first time), for activity A is: $400, E is $415 and all other activities is : $100 (per week per activity). The crashing cost, second week and onwards(crashing second time), for activity A is $1000 per week, E is $1200 per week and for all other activities is $200 per activity per week. You have a maximum crashing budget of $2505. The maximum possible reduction in the project duration will be: a. 2 weeks b. 3 weeks c. 4 weeks d. 5 weeks e. 6 weeks
For a given activity, the: most optimistic time to complete the project is 8, the most pessimistic time to complete the activity is at 32, compute the estimated time to complete the activity if the most likely to complete is at 2
(g) Using the IF function, write a formula in J38 to display "Yes" if the activity is critical and display "No" if the activity is not critical. Copy the formula to cells J39:J44.To calculate the entire project's variance, we simply add variance for activities on the critical path. Screenshot attached tahnks!!!

Coleman Rich Control Devices, Inc., produces custom-built relay devices for auto makers. The most recent project undertaken by Rich requires 14 different activities. Rich's managers would like to determine the total project completion time (in days) and those activities that lie along the critical path. The appropriate data are shown in the following table: Activity A B с D E F G a) The expected completion time of the project = a 4 1 6 5 1 2 1 Time (days) m 6 2 6 8 9 3 7 b 7 3 6 11 18 6 8 Immediate Predecessor(s) A A B, C D D Activity a H 4 I 1 J 2 K 8 2 1 6 M N days (round your response to two decimal places). Time (days) = m 4 6 5 9 4 2 8 b 6 8 7 11 6 3 10 Immediate Predecessor(s) E, F G, H K L, M The activities that represent the project's critical path are b) If the time to complete the activities on the critical path is normally distributed, then the probability that the critical path will be finished in 53 days or less = decimal places). c) Using the standard normal table, the…
