1. The expected completion time of the project = ? days (round your response to two decimal places)

2. the activities that represent the projects critical path are __?__

3. If the time to complete the activites on the critical path is normally distributed, then the probablitity that the critical path will be finished 55 days or less = ? (round your response to two decimal places).

4. Using the standard normal table, the number of days that would result in 99% probablitily 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) a m b Immediate Predecessor(s) E, F G H Activity B C D E F G Time (days) a m b 4 5 7 1 3 5 5 5 5 4 10 13 3 10 17 3 6 3 Immediate Predecessor(s) Activity H 1 A J B, C L D M N 4 2 2 7 2 1 4 6 4 10 5 2 8 NAON 0 co K L, M
