QUESTION 2

A lab rat has been trained to press a lever. The rat was last fed 10 hours before the experimental session. When the rat is placed in the Skinner box it only presses the lever when the light above the lever is lit. Every fifth time the rat presses the lever, a food pellet drops into the food cup.
