ieman Rich Control Devices, Inc, produces custom-built relay devices for auto makers. The most recent project ndertaken by Rich requires 14 different activities. Rich's managers would like to determine the total project completion me (in days) and those activities that lie along the critical path. The appropriate data are shown in the following fable: a) The expected completion time of the project = days (round your response to (wo decimal places) The activities that represent the project's 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 finished in 55 days or less = (round your response to two decimal places) c) The number of days that would result in 99% probability of completion is = days (round your rosponse to two decimal places) ieman Rich Control Devices, Inc, produces custom-built relay devices for auto makers.
