Project Completion and Activity Time

You will be given a list of the activities of a project with completion time estimate for each activity. You will be asked to calculate 7 questions.
(a) Calculate the expected duration of each activity. Also, calculate the expected duration of each path.
(b) Calculate the variance of each activity and variance of each path. Also, calculate the standard
deviation of each activity and the standard deviation of each path.
(c) Identify the critical path(s) (based on the expected durations).
(d) What is the probability that the project can be completed within 49 weeks? What is the probability
that the project will NOT be completed within 49 weeks?
(e) What is the probability that the project will require 47 weeks or more? What is the probability that
the project will NOT require more than 47 weeks?
(f) What is the probability that the project will be completed between 45 and 50 weeks?
