evolutionary theories often emphasize that humans have adapted to their physical enviornment. one theory hypothesizes that people should spontaneously follow a 24-hour cycle of sleeping and walking-even iff they are not exposed to the usual pattern of sunlight. to test this notion, eight paid voulenteers were placed (individually) in a room in which there was no light from the outside and no clocks or other indications of time. they could turn the lights on and off as hey wished. after a month in the room, each individual tended to develop a steady cycle. their cycles at the end of the stufy were as follows: 25, 27, 25, 23, 24, 25, 26, and 25. use the steps of hypothesis testing.
