The following table represents a project with four activities.All times are in weeks.
Activity | Immediate Predecessor | Optimistic Time | Most Likely Time | Pessimistic Time |
A | - | 4 | 8 | 16 |
B | - | 7 | 8 | 9 |
C | A | 6 | 10 | 18 |
D | B | 5 | 13 | 18 |
A. According to the data in the table. What is the criticalpath?
B. According to the data in the table, what is the minimumexpected completion time for the project?
C. According to the table there are four activities in theproject. Assume the normal distribution is appropriate to use todetermine the probability of finishing by a particular time. If youwished to find the probability of finishing the project in 21 weeksor fewer. It would be necessary to find the variance and then thestandard deviation to be used with the normal distribution. Whatvariance and standard deviation would be used?
D. According to the table, There are four activities in theproject. Assume the normal distribution is appropriate to use todetermine the probability of finishing by a particular time. Whatis the probability that the project is finished in 20 weeks orfewer.
