If you use the formula [tex]ME = \frac{1}{\sqrt{n}}[/tex] then,

[tex]ME = \frac{1}{\sqrt{n}}[/tex]

[tex]0.063 = \frac{1}{\sqrt{n}}[/tex]

[tex]0.063*\sqrt{n} = 1[/tex]

[tex]\sqrt{n} = \frac{1}{0.063}[/tex]

[tex]\sqrt{n} \approx 15.87301587[/tex]

[tex]n \approx (15.87301587)^2[/tex]

[tex]n \approx 251.952632809271[/tex]

[tex]n \approx 252[/tex]

So we need roughly 252 people

Answer: Choice C) 252
