Which of the following is a correct description of the t-distribution?

Select one:

a. It is the best distribution to use with small sample sizes.

b. There are fewer scores in the tails than in a normal distribution.

c. It is equal to a normal distribution with infinite degrees of freedom.

d. It is the best distribution to use when the population might be right or left skewed.

Answer #1

Answer with proper reasoning for the description of the t-distribution is as below.

a. This may not be the best distribution to use for small sample sizes.

b. is wrong. T-distribution has fatter tails than normal distribution and thus more scores in the tail than normal distribution. B is wrong.

c. With infinite degrees of freedom, the t distribution is the same as the standard normal distribution.

d. is false. It is not the best distribution to use when the population might be right or left skewed.
