Let T be the continuous random variable given t normal-usage lifetime, in years and parts of years, of such a card. The sample is grouped HISTOGRAM function and used to plot an approximation of the p.d.f ., fT . Since the shape of the approximation suggests that T might be exponential, we have points for both the sample and an exponential random variable whose mean is the same as sample mean.
