g True or False: A sample of size 25 provides a sample variance of 400. The standard error in this case, equal to 4, is best des

Tpy6a [65]

Answer:

True.

Step-by-step explanation:

If we have for a sample of size n=25 a sample variance of 400, the standard error can be written as:

$\sigma_s=\dfrac{\sigma}{\sqrt{n}}=\dfrac{\sqrt{400}}{\sqrt{25}}=\dfrac{20}{5}=4$

This way of calculating the standard error is the same used for estimating the standard deviation of the sample means for samples of size n=25.
