b) The expected completion time of the critical path = ______weeks (round your response to two decimal places).

The expected completion time of the path other than the critical path = _____ weeks (round your response to two decimal places).

c) The variance of the critical path = _____ weeks (round your response to two decimal places).

The variance of the path other than the critical path = ______weeks (round your response to two decimal places).

d) If the time to complete the activities on the critical path is normally distributed, then the probability that the critical path will be finished in

23 or 22 weeks or less = ______ (enter as a probability and round your response to two decimal places).

e) If the time to complete the activities on the non critical path is normally distributed, then the probability that the non critical path will be finished in

23 or 22 ______weeks or less = enter your response here (enter as a probability and round your response to two decimal places).

The estimated times and immediate predecessors for the activities in a project at Howard Umrah's retinal scanning company are given in the f table. Assume that the activity times are independent. ) This exercise contains only parts a,b,c,d, and e
