Which of the following statements about the relationship between the standard normal distribution and the Students t distribution are true?

Select one:

a.

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

b.

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.

c.

For a given value of n, values from the t distribution are never less than values from the standard normal distribution.

d.

All of the above.

e.

None of the above.
