Using PERT, Adam Munson was able to determine that the expected project completion time for the construction of a
pleasure yacht is 21 months, and the project variance is 16.
a) The probability that the project will be completed in 25 months =
(round your response to four decimal places).
b) The probability that the project will be completed in 37months = ☐ (round your response to four decimal places).
c) The due date that yields a 95% chance of completion = ☐ months (round your response to two decimal places)..
A company is willing to develop their rocket before the end of current financial
year which is now 28 weeks away. The chief engineer of the company has
decided to use PERT technique in order to plan, schedule and control program
of development for the data given in table below.
What is the probability that the program will be completed by the end of the
current financial year? (all durations are in weeks).
