Question

How is the t-distribution similar to the standard normal z-distribution?

Multiple Choice

• Both are skewed distributions.

• Both are continuous distributions.

• Both are discrete distributions.

• Both are families of distributions.

Answer 1

Answer:

Both are continuous distributions.

Explanation:

Both are skewed distributions. False, the t distribution can be skewed but the z distribution is symmetric around the mean value.

Both are continuous distributions. True, because both of the distributions are defined at any value hence continuous in nature.

Both are discrete distributions. False, because both of the distributions are continuous in nature.

Both are families of distributions. False, because these distributions do not have a shape parameter which means only one shape is defined hence no families of distributions.
