The t distribution is similar to the z distribution because _________________.

	A.	as the degrees of freedom go to infinity, the t distribution converges to the z distribution
	B.	both have asymptotic tails-that is, their tails become closer and closer to the horizontal axis but never touch it
	C.	as the degrees of freedom go to infinity, the t distribution converges to the z distribution and both have asymptotic tails-that is, their tails become closer and closer to the horizontal axis but never touch it are correct
	D.	Neither as the degrees of freedom go to infinity, the t distribution converges to the z distribution nor both have asymptotic tails-that is, their tails become closer and closer to the horizontal axis but never touch it is correct
