A project with nine activities are shown below. Activity X, IP = none, 16 days Activity G, IP = F, 25 days Activity F, IP = X, 9 days Activity N, IP = M, P, 21 days Activity P, IP = F, 25 days Activity M, IP = K, 12 days Activity R, IP = P, G, 24 days Activity K, IP = X, 27 days Activity Z, IP = N, R, 11 days Activity X is the first activity in the project. Furthermore, the project is completed when activity Z is finished. Perform forward and backward passes of CPM. Answer the questions shown below. The project completion time is days EF of activity N = LS of activity N = EF of activity P = LS of activity P = Slack of activity P = days Path X-K-M-N-Z is critical (write yes or no) Path X-F-P-N-Z is critical (write yes or no)
