Chapter 10: Using Statistical Sampling: Taking Samples
He begins this chapter with the problem of a confectionary company which makes loads of gum balls. They want to increase their sale and want to know how long does the gum balls hold their taste. They hire tasters who taste every gum ball this company produces which leaves company no gum balls to sell plus they are also incurring huge debt paying for the dental plans of their tasters.
So the problem is that the tasters don’t have to taste every gum ball.
