If the R square value is 0.73, which statement below is correct?		R square is the square root of r.
	R square is the coefficient of correlation.
	R square of 0.73 tells us this is a postive correlation. R square of -0.73 would be a negative correlation.
	We can tell that the coefficient of correlation is 0.73 which is a strong correlation. 0.25 is weak, and 0.5 is moderate.
	We can explain 73% of the change in the dependent variable by changes in the indpendent variable.
