A study team is examining the effect of a culturally focused dance intervention on physical activity in Latino adults with type 2 diabetes. Using a pretest-post-test design, measures of physical activity were taken before and after the dance intervention. An appropriate statistical test to determine the effect of the dance program on activity levels would be:

	A.	multiple linear regression.
	B.	pearson correlation.
	C.	paired T-test.
	D.	frequency distribution.
