What is the solution to this question?

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 ( days) and those activities that lie along the critical path. The appropriate data are shown in the following table Time (days) Time (days) immediale Immediate Predecessor(s) Activity m m Activity A Predecessor H EF B 1 G.H C A J D A K 7 A E B, C L 5 F 2 2 5 D 7 M 1 K 2 D N B G 11 LM a) The expected completion time of the project days (round your response to two decimal places) The activities that represent the projects critical path are b) If the time to complete the activities on the critical path is normally distributed, then the probability that the critical path will be frished in 54 days or less-round your response to two decal places days (round your response to two decimal places c) Using the standard normal table, the number of days that would result in 99% probability of completion 3 1 5 6 3 7 2 5 8 10 b 8 5 6 13 19 . 3 2 2 3 6 6 10 D 7 10 7 13 6 6
