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
[tex]SE=\frac{\sigma}{\sqrt{n}}[/tex]
Where, [tex]\sigma=22[/tex] is the standard deviation of a normally distributed population
n=4 is the sample size
Substitute the value,
[tex]SE=\frac{22}{\sqrt{4}}[/tex]
[tex]SE=\frac{22}{2}[/tex]
[tex]SE=11[/tex]
Therefore, the standard error is 11.
