When activity times are uncertain,total project time is normally distributed by considering the overall mean being equal to the sum of the means of all of the critical activities.

Question

Quizplus · Accepted Answer

When activity times are uncertain, the total project time is not a fixed value, but rather a probability distribution. One common distribution used for this purpose is the normal distribution. In this case, the overall mean of the project duration is equal to the sum of the means of all of the critical activities. This is because the mean of a sum of random variables is equal to the sum of their means. Therefore, the statement is true.
