Professor Jacob wants to study how easily people make friends by varying the number of minutes people talk with a stranger. She assigns people who are extroverts to the 5 minute condition and people who are introverts to the 10 minute condition. This study can be criticized because:

		the experimenter did not use random assignment.
		the participants are not representative of the larger population.
		this study uses correct methodology.
		the experimenter has biased the participants by providing unintentional cues about correct responses.

		Very high levels of arousal are associated with optimal performance.
		Level of arousal has no impact on performance.
