Researchers found 300 adults who eat soup every night. The first week the subjects weregiven the same amount of soup in either a circular bowl or a square bowl. Subjects were thenasked to eat the soup at their own pace while reading. The time it took to finish their soup wasmeasured. During the second week, the subjects were given the other shaped bowl and askedto complete a crossword. Again, the time it took to finish their soup was measured. The type ofbowl given in the first week was determined randomly. The researchers found that the time tocomplete the bowl of soup was significantly faster for the circular bowl. a.What type of experimental design is this?b. Who are the subjects?c.
