A group of psychologists is studying the effect of listening to
music on the ability to
a person to quickly complete a simple task. They recruit a group of
84
volunteers to participate in an experiment. Each subject will sit
at a table in a
small room and you will be asked to complete a puzzle. Some
subjects
they will hear music playing in the room (be it classical, rock or
country music),
while the others will not listen to music (a control group). The
time will be measured
it takes each subject to complete the puzzle.
Psychologists anticipate different outcomes for men and women, so
the
experiment will be carried out separately for the 36 male
volunteers and the 48
volunteer women.
