When there are ? degrees of freedom, the t_? distribution A)can no longer be calculated. B)equals the standard normal distribution. C)has a bell shape similar to that of the normal distribution, but with "fatter" tails. D)equals the $X _ { \infty } ^ { 2 }$ distribution.

When there are ∞ degrees of freedom, the t_∞ distribution equals the standard normal distribution. As the degrees of freedom increase, the t-distribution approaches the standard normal distribution, and when there are an infinite number of degrees of freedom, the t-distribution becomes the standard normal distribution.
