Question

16. What is the margin of error for a poll with a sample size of 200 people? Round your answer to the nearest hundredth of a percent. %

Answer 1

The margin error is given by:

$\frac{1}{\sqrt[]{n}}\times100$

n=200

Thus, we have:

$\begin{gathered} \frac{1}{\sqrt[]{200}}\times100 \\ \Rightarrow7.07 \end{gathered}$
