	5.	The scatter plot shows the relationship between number of weekly meals at fast food restaurants and blood cholesterol level for 25 adults in a correlational study. Describe the independent and dependent variables of the graph and what the graph indicates.
		A.	The independent variable is blood cholesterol level. The dependent variable is the number of meals per week at a fast food restaurant. In the study, people who ate more often at fast food restaurants generally had higher blood cholesterol levels.
		B.	The independent variable is blood cholesterol level. The dependent variable is the number of meals per week at a fast food restaurant. In the study, people who ate more often at fast food restaurants generally had lower blood cholesterol levels.
		C.	The independent variable is the number of meals per week at a fast food restaurant. The dependent variable is blood cholesterol level. In the study, people who ate more often at fast food restaurants generally had higher blood cholesterol levels.
		D.	The independent variable is the number of meals per week at a fast food restaurant. The dependent variable is blood cholesterol level. In the study, people who ate more often at fast food restaurants generally had lower blood cholesterol levels.
