A Dean is evaluating the student teaching evaluations for a particular faculty member. The Dean is interested in the following item: The instructor promotes critical thinking. This is measured on a 7-point scale, with 1 = completely disagree and 7 = completely agree. The midpoint of the scale is 4.0 and descriptive statistics reveal that the instructor averaged a 4.2 on this item. To determine if the score is significantly higher than the scale's midpoint, the Dean should conduct a(n):

	ANOVA and post-hoc tests.
	chi-square test of independence.
	single-sample t-test.
	independent-samples t-test.
