    Bill Fennema, president of Fennema Construction,
    has developed the tasks, durations, and predecessor relationships in
    the following table for building new motels. Draw the AON network
    and answer the questions that follow.
    Time Estimates (in weeks)
    Activity Immediate Predecessor(s) Optimistic Most Likely Pessimistic

    A ----- 4 8 10
    B A 2 8 24
    C A 8 12 16
    D A 4 6 10
    E B 1 2 3
    F E,C 6 8 20
    G E,C 2 3 4
    H F 2 2 2
    I F 6 6 6
    J D,G,H 4 6 12
    K I,J 2 2 3

    a) What is the expected (estimated) time for activity C?
    c) Based on the calculation of estimated times, what is the critical
    d) What is the estimated time of the critical path?
