• Exercise #9:
  • Review the following network (this is the same network from Exercise #8) and the estimated activity times in the chart below:

• _Activity_	_____a____	____m____	____b____
  A	6.5	7.5	14.5
  B	8.5	10.5	12.5
  C	2.5	3.5	4.5
  D	6.5	7.5	8.5
  E	5.5	5.5	9.5
  F	5.5	7.5	9.5
  G	4.5	6.5	8.5
  H	2.5	3.5	3.5

• For Exercise #9, assemble a table showing the Expected Duration, and Variance of each activity, then calculate the probability the project will finish in 25, 27, and 30 days (Note: this is different than the directions given in the textbook).
