Assume you have a normal distribution representing the likelihood of completion times.The mean of this distribution is 10, and the standard deviation is 3.The probability of completing the project in 7 or fewer days is the same as the probability of completing the project in 13 days or more.

Question

Quizplus · Accepted Answer

In a normal distribution, the probabilities on either side of the mean at equal distances are the same. Since 7 is 3 units below the mean (10) and 13 is 3 units above the mean, the probabilities of completion times less than 7 days and more than 13 days are equal.
