RESEARCH STUDY 9.2
Dr. Acitelli studies sleep and sleep disorders. She is curious as to whether falling asleep in front of a television set causes people to fall asleep more slowly than falling asleep regularly. She recruits a sample of 60 middle-aged women from a local church who reported no history of sleep problems. She creates three conditions. All participants come to the sleep lab for three nights in a row and experience all three conditions. In the first condition (A) , participants fall asleep in front of a television that is off. In the second condition (B) , participants fall asleep in front of a television that is turned on to the same 24-hour news channel. In the third condition (C) , participants fall asleep in front of a television that is turned on to the same 24-hour news channel but is muted. With the use of an electroencephalograph (EEG) , the researcher measures how long it takes participants to fall asleep.
-Refer to Research Study 9.2 above to answer the following question. Given that there are three conditions/levels of the independent variable,how many orders of the conditions are possible in Dr.Acitelli's study?

A) Three
B) Six
C) Nine
