a) the expected completion time of the project

- the activities that represent the projects critical path are?

b) what is the probability of being done in 54 days?

c) what date results in a 99% probability of completion

Coleman Rich Control Devices, Inc., produces custom-built relay devices for auto makers. The most recent project undertaken by Rich requires 14 different activities. Rich's managers would like to determine the total project completion time (in days) and those activities that lie along the critical path. The appropriate data are shown in the following table: Time (days) Time (days) Immediate Predecessor(s) Immediate Predecessor(s) m Activity m Activity A H 4 E, F B 1 2 G, H 3 1 6 2 J A D 5 A K 6 2 B, C L 2 F 1 8 1 D M G 6 8 N D 1 7 8 a) The expected completion time of the project = days (round your response to two decimal places).
