(b) What duration will have 95% confidence for project completion? (c) If the average duration for activity F increases to 14 days, what will be its effect on the expected project completion time which will have 95% confidence? For standard normal Z=1.6545, area under the standard normal curve from 0 to Z=0.45 ) (d) What will be the probability of the project completion on or before 27 days
