Explanation:
Detailed explanation-1: -If your expected value is 110 and the standard deviation is 12, which of the following is true? There is approximately a 68 percent chance of completing this activity in 98 to 122 days.
Detailed explanation-2: -The duration of the project is the sum of duration of each activity along the critical path.
Detailed explanation-3: -When activity times are uncertain, an activity’s most likely time is the same as its expected time. The earliest finish time for the final activity is the project duration. The length of time an activity can be delayed without affecting the project completion time is the slack.
