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)..
