activity tirnest are indoperisont This exerowe cantans onty parts a, b, c, a and a. a) Based on the activity time estimates, the expected times and variance for each of the activities are (round your rosponse fo ho decimal pliaces) b) The expected completion time of the critical path = weeks (round your response to fwo decirmal places) The expected completion time of the path other than the critical path = weeks (round your response to two decinal places) b) The expected completion time of the cribical path = weeks (round your respanse fo fwo docimal places). The expected completion time of the path other than the critical path = weoks (round your response to two decinal places) c) The variance of the critical path = Weoks (round your response to No docimal plinces). The variance of the path other than the critical path = woeks (round your response to fwo decimal places) d) If the time fo complete the activities on the critical path is nomally distributed, then the probahaity that the citical path will be finished in 21 wecks or less = arotiability and rourd your response to fwo decimal places). If the time to complete the activities on the non critical path is nomally distributed, then the probability that the non critical path wil be finishad in 21 wieks or less = s a probabily and round your response to two decimal piaces)
