... these will be somewhat different, reflecting not only errors in our method of measuring but also real variations in the actual diameter. Again, in principle, there is no limit to the number of pistons that could be produced and measured. In both our examples, we define the “population” as the number ...

... Exponential: lifetimes of devices with no wear-out (“memoryless”), interarrival times when the arrivals are at random Gamma: used to model lifetimes, related to many other distributions Lognormal: lifetimes (similar shape to Gamma but with longer tail) Beta: not equally likely over an interval ...

... Because the shape of the population distribution is unknown and could be nonnormal, in parametric tests data normality resembles the sampling distribution, not the population. In other words, a test statistic from the sample will be compared against the sampling distribution ...
