A typical activity i-j in a CPM network has activity duration (tij) of 2.5 time units. The earlier expected time $T_{L}^{i}$ and latest allowable occurrence time $T_{E}^{i}$of event i are computed as 8 and 11 units respectively. The corresponding times of event j, i.e $T_{E}^{j}$ and $T_{L}^{j}$ are respectively 13.5 and 13.5 units. Find the three floats of the activity i-j.
