Question

A manufacturer of food products produces liners that are sealed at the top by applying heated jaws to the liner after the package is filled. The customer peels the sealed pieces apart to open the package. The manufacturer wants to know whether the temperature of the jaws has any effect on the force required to open the package. To answer this question, engineers prepare 20 pairs of pieces of package liner. They seal five pairs at each of 250oF, 275oF, 300oF, and 325oF. Then they measure the peel strength of each seal.

(a) What are the experimental units?
