<h3>What is sample size?</h3>
The formula for margin of error is;
E = zs/√n
where;
s is standard deviation
n is sample size
Thus;
Since we want to cut margin of error in half from 3 percentage points to 1.5 percentage points, since the standard deviation and z-score will remain the same, the way to do it will be to increase the sample size by multiplying it by 4.

11/P = B-6
(11/P) + 6 = B
