Using PERT, Adam Munson was able to determine that the expected project completion time for the construction of a pleasure yacht is 15 months, and the project variance is 4, the probability that the project will be completed in 16 months is _ (Round to one decimal place)

approximately 0.7

Explanation:

Pert Analysis is used to compute/sum up the various variances of a project along its critical path

using PERT

The mean value of project ( estimated project time ) = 15

project variance б = 4

standard deviation = б = 2

probability that project will be completed on or before 16 months  

= P ( X ≤ 16 )

this means  Z ≤ where X = 16

= Z ≤ 1

using the the normal distribution appendix for the Z value the probability of completing the project in 16 months would approximately be 0.7
