Question

Which of the following statements is true about the t-distribution?

A)Since population standard deviation is usually known, the estimated standard deviation uses the population standard deviation to estimate the sample standard deviation.

B)For very large sample sizes (over 100), the t-distribution has the same properties (shape and critical values) as the Normal curve.

C)Like the Normal distribution, the t-distribution is not symmetric for small n.

D)For very small sample sizes (less than 10), the t-distribution has the same properties (shape and critical values) as the Normal curve.

Explanation / Answer

For very large sample sizes (over 100), the t-distribution has the same properties (shape and critical values) as the Normal curve.
