Conditions Country Music (CW: Whiskey River), Classic Rock (R: Hotel California), or No Music (NM). Thirty-Three college students participated. Eleven participants were randomly assigned to study while listening to Country Music for 2 hours, a different 11 students were randomly assigned to study while listening e Classic Rock for 2 hours, and a different 11 students were randomly assigned to study while listening to No Music for 2 hours. The data are presented below. The researcher wants to maximize the Power of the test.
