Use this information to answer the following questions.
A university needs to prepare a banquet for its graduating seniors.The following information describes the relationships between the activities that need to be completed for this banquet.
$$\begin{array} { c l l } & \text { Immediate } \\\text { Activity } & \text { Predecessors } \\ \text { A } & - \\\text { B } & - \\\text { C } & \text { A, B } \\\text { D } & \text { C } \\\text { E } & \text { C } \\\text { F } & \text { D, E } \\\text { G } & \text { E } \\\text { H } & \text { F, G }\end{array}$$
-Refer to the information above.Assume that the catering manager was able to estimate the number of hours needed to complete each activity as follows.
$$\begin{array} { c c c c } \text { Activity } & \text { Optimistictime } & \text { Most Likely Time } & \text { Pessimistic Time } \\ \text { A } & 2 & 3 & 5 \\\text { B } & 4 & 6 & 7 \\\text { C } & 3 & 4 & 5 \\\text { D } & 2 & 3 & 5 \\\text { E } & 1 & 2 & 3 \\\text { F } & 5 & 7 & 11 \\\text { G } & 6 & 8 & 9 \\\text { H } & 4 & 6 & 7\end{array}$$
