Consider a PERT network as given below:
The expected activity time is as shown in the network above. The probability of completion of the above project in 24 days is 95%. Calculate the expected activity time for activity 2 - 3, if the standard deviation for the project is 2.5.
P(%) | 90 | 94 | 97 |
z | 1.3 | 1.5 | 1.8 |
