solve d, e, f according to the questions before

e) If the time to complete the activities on the non critical path is normal distributed, what is the probability that this path will be finished in 22 weeks or less? Compute Z.

f) The smallest probability across all paths is the probability of project finishing in time.

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 =21.16 weeks (round your response to two decimal places). The expected completion time of the path other than the critical path =20 weeks (round your response to two decimal places). c) The variance of the critical path =6.47 weeks (round your response to two decimal places). The variance of the path other than the critical path =0.55 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 22 weeks or less = response to two decimal places).
