Chapter 17, Problem 9P
(a)
Summary Introduction
To determine: The probability of the project will take more than 10 weeks to complete where time is given in weeks and the construction of a network diagram for the information given with mean and standard deviation.
Introduction: The time required to complete any activity is estimated with optimistic (optimum time), pessimistic (time required in worst condition), and most likely time (probable time).
(b)
Summary Introduction
To determine: The probability if the project will take 16.5 or more weeks to complete with the given information of mean and standard deviation.
Introduction: The time required to complete any activity is estimated with optimistic (optimum time), pessimistic (time required in worst condition), and most likely time (probable time).
