Details: Complete problems 3.11 and 3.17 (parts c, d, e, and f) in the textbook. Submit one Excel file. Put each problem result on a separate sheet in your file. **book is attached if the problems displayed seem cumbersome.** 3.11 Dave Fletcher (see Problem 3.10) was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined. Here are the activity times: ACTIVITY TIME (WEEKS) ACTIVITY TIME (WEEKS) A 6 E 4 B 7 F 6 C 3 G 10 D 2 H 7 3.17 Bill Fennema, president of Fennema Hospitality, 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.
