ANSWER:
902 people
STEP-BY-STEP EXPLANATION:
We have that the margin of error is given by the following formula:
[tex]e=\frac{1}{\sqrt[]{n}}\cdot100\text{\%}[/tex]
We know the value of the error, therefore we can replace and calculate the sample size:
[tex]\begin{gathered} 3.33\text{\%}=\frac{1}{\sqrt[]{n}}\cdot100\text{\%} \\ \frac{1}{\sqrt[]{n}}=0.0333 \\ \sqrt[]{n}=\frac{1}{0.0333} \\ n=\mleft(\frac{1}{0.0333}\mright)^2 \\ n=901.8\cong902 \end{gathered}[/tex]
The sample size will be 902 people
