Given:

Standard error = 4

Population standard deviation = 16

To find:

The value of n.

Solution:

The formula of standard error is:

$SE=(\sigma)/(√(n))$

Where, SE is standard error ,
$\sigma$ is population standard deviation and n is the total number of elements.

Substituting
$SE=4,\sigma=16$ in the above formula, we get

4=(16)/(√(n))

√(n)=(16)/(4)

√(n)=4

Taking square on both sides, we get

n=4^2

n=16

Therefore, the value of n is 16.
