This exercise contains only parts a,b,c,d, and e. a) Based on the activity 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 = c) The variance of the critical path = The variance of the path other than the critical path = 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 21 weeks or less = round your response to two decimal places). weeks (round your response to two decimal places). weeks (round your response to two decimal places). weeks (round your response to two decimal places). weeks (round your response to two decimal places).
