Answer

As the sample size (n) gets bigger, the values of X (t distribution) get closer to the values of Z (normal distribution).

Answer

The larger the sample size, the closer the t distribution is to the standard normal distribution, so in practice if we have a big enough sample, we can just use the standard normal distribution instead of the t distribution.
