Question: You are given the following data concerning the activities in a project (numbers refers to days) Ignore a and b

a. Compute the speciation ( \(\mu \) _i) and the variance ( \(\sigma _{i}^{2}\) ) of the time required to compete each activity

b. Draw a network diagram, and the find the critical path by inspection. What is the expected length of the critical path?

c. Assume the times for each activity are independent and that the times required to complete a path is normally distributed. Compute the probalbity that path ACD will be completed in less than 16 days. Also compute the probability that path BE will be completed in less than 16 days.

d. What is the probability that the project will be completed in less than 16 days?
