Question

If the standard deviation of a normally distributed population is 22.0 and we take a sample of size 4 then the standard error is

Answer 1

Answer:

The standard error is 11.

Step-by-step explanation:

Given : If the standard deviation of a normally distributed population is 22.0 and we take a sample of size 4.

To find : The standard error ?

Solution :

The standard error formula is

$SE=\frac{\sigma}{\sqrt{n}}$

Where, $\sigma=22$ is the standard deviation of a normally distributed population

n=4 is the sample size

Substitute the value,

$SE=\frac{22}{\sqrt{4}}$

$SE=\frac{22}{2}$

$SE=11$

Therefore, the standard error is 11.
