The Table below provides data on activities for building a trucking weigh-station. Based on this data, which of the following is the Critical Path? Note: You will likely need to draw the same Network Diagram, and calculate much of the same information, for this question and the next. Std.

Based on this data, and your calculations from the previous question, what is the Probability (likelihood) that the Project Manager will complete the project within 69 days (D) of the time the project started? Hint, here is the formula your will use: Z = (D - ) / ). Note: You will need to access a Z-Table like the one shown on page 315 (see Table 8.5) of the Meredith text (10th Edition).
