Recent study of undergraduates-MGMAT

by joshua868 » Sat May 28, 2011 7:32 pm
A recent research study of undergraduate students analyzed the effects of music on human emotions. Each of the 200 participants attended at least 1 two-hour concert of classical music per week over the course of 12 weeks of their spring semester. At the end of the experiment, all of the students filled out a questionnaire assessing their emotional state. Based on the results of the questionnaires, all of the 10 students who attended the greatest number of concerts reported lower stress levels and higher satisfaction with their lives. Also, most of the 20 students who attended the fewest number of concerts reported below-average levels of emotional comfort.

Which of the following must be true based on the evidence presented above?
a)Most of the 200 participants improved their emotional state and lowered their stress levels.
b)During each week of the experiment, the participants spent at least 2 hours less on their academic work as a result of concert attendance.
c)Listening to classical music for at least 2 hours per week improves the emotional well-being of the majority of young adults.
d)More than 6 participants attended at least 14 concerts during the course of the experiment.
e)At least some of the students participated in the study in order to gain free access to classical concerts.

Which of the following must be true based on the evidence presented above?

a. Most of the 200 participants improved their emotional state and lowered their stress levels.

b. During each week of the experiment, the participants spent at least 2 hours less on their academic work as a result of concert attendance.

c. Listening to classical music for at least 2 hours per week improves the emotional well-being of the majority of young adults.

d. More than 6 participants attended at least 14 concerts during the course of the experiment.

e. At least some of the students participated in the study in order to gain free access to classical concerts.


Also the problem with option C is that it has the word majority which means more than 50% and the stimulus talks about only 30 students out of 200 students. So that is a flaw in option C.
IT IS TIME TO BEAT THE GMAT
