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 4. a) The probability that the project will be completed in 17 months = b) The probability that the project will be completed in 20 months = c) The probability that the project will be completed in 23 months = d) The probability that the project will be completed in 25 months = e) The due date that yields a 95% chance of completion = (round your response to four decimal places). (round your response to four decimal places). (round your response to four decimal places). (round your response to four decimal places). months (round your response to two decimal places).
