We shall use the z-table to solve for the margin of error. The formula for the margin of error is
$E=z_{\alpha /2}\cdot \frac{\sigma }{\sqrt{n}}$

The value of z will be taken with the assumption that the significance level is 5%. So, α=0.025. Then $z_{\alpha \:/2}=1.96$ .

So, based from this, the margin of error is
$E=z_{\alpha /2}\cdot \frac{\sigma }{\sqrt{n}}=1.96\cdot \frac{0.043}{\sqrt{15}}=0.02$

The margin of error is about 2%.
