Question No. 5 Activity Dependency optimistic Most likely Pessimistic A 6 8 IB 4 5 IC | A 2 3 4 ID B x-1 x+2 x = (last digit of your roll no. +4) E B 3 4 F 18 10 15 IG EF 3 4 H C.D 2 2.5 1. By using three estimates for each activity, find: [2] 1.1. Estimated time 't." Activity standard deviation 's' 2. Draw PERT network after calculating the events' estimated times and standard deviations.
