The information in the table below is available for a large fund-raising project.a. Determine the critical path and the expected completion time of the project.b. Plot the total project cost, starting from day 1 to the expected completion date of the project, assuming the earliest start times for each activity. Compare that result to a similar plot for the latest start times. What implication does the time differential have for cash flows and project scheduling?
