Find "n" if the Standard Error of Mis 4 and the population standard deviation is 16.

Given:

Standard error = 4

Population standard deviation = 16

To find:

The value of n.

Solution:

The formula of standard error is:

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

Substituting in the above formula, we get

Taking square on both sides, we get

Therefore, the value of n is 16.
