This exercise contains only parts a,b,c,d, and e. a) Based on the given three time estimates, the expected times and variance for each of the activities are (round your response to two decimal places): b) The expected completion time of the critical path = The expected completion time of the path other than the critical path = weeks (round your response to two decimal places). 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)
