How do the t_dfand z distributions differ? A) There is no difference between the t_dfand z distributions. B) The z distribution has broader tails (it is flatter around zero). C) The t_dfdistribution has broader tails (it is flatter around zero). D) The z distribution has asymptotic tails,while the t_dfdistribution does not.

The t-distribution has broader tails than the standard normal (z) distribution. The degrees of freedom (df) parameter in the t-distribution determines the shape of the distribution, with larger df resulting in a shape closer to the normal distribution. However, even with df=1 (as in tS1U1B1df), the t-distribution has heavier tails than the normal distribution.
