4 What is true about the Kolmogorov-Smirnov Test

	It is often used to fit a curve
	It must be used to fit a curve
	it uses the uniform norm of the curve and observed data
	it uses the uniform norm on the CDF of the curve and the CDF of the observed data
	it uses the L1-norm on the CDF of the curve and the CDF of the observed data
