a) The expected completion time of the project = days (round your response to two 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 53 days or less = (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 = days (round your response to two decimal places)
