The number of hours a lightbulb burns before failing varies from bulb to bulb. The population distribution of burnout times is s

trongly skewed to the right. The central limit theorem says that
(a) as we look at more and more bulbs, their average burnout time gets ever closer to the mean m for all bulbs of this type.
(b) the average burnout time of a large number of bulbs has a sampling distribution with the same shape (strongly skewed) as the population distribution.
