Calculate the Variance

The man-hour estimate for test and evaluation was based on using expert opinion to come up with optimistic, pessimistic and most likely positions. This resulted in a triangular distribution with a minimum estimate of 425 hours, a most likely estimate of 500 hours, and an expected maximum of no more than 650 hours. Calculate the variance of this distribution.

A) 525
B) 2188
C) 92604
D) 4219
