A researcher wanted to see whether the climate in a room affects the time it takes to reach REM sleep (in minutes) in a bedroom that is 80°. On the first night, participants were given a ceiling fan that circulated the air in the room at a moderate speed. On the second night, the same participants slept in a room without any air circulation.
