Consider that you are fabricating reaction vessels that are to be rated for 500 psi. The vessels obviously have a range of bursting pressures...but you certainly can't measure all of the bursting pressures, because then you would have nothing to sell. Suppose you measure the bursting pressure of a sample of the vessels. You ask the question: is there any evidence that the average bursting pressure of the population would be less than 500 psi? You don't want to sell...
