Sagot :

ANSWER:

1.83%

STEP-BY-STEP EXPLANATION:

We have that the formula for the margin of error is as follows:

[tex]e=\frac{1}{\sqrt[]{n}}\cdot100\text{\%}[/tex]

We plug in the value of the sample size and calculate the error value, like this:

[tex]\begin{gathered} e=\frac{1}{\sqrt[]{3000}}\cdot100\text{\%} \\ e=\frac{1}{54.77}\cdot100\text{\%} \\ e=1.8257\text{\% }\cong1.83\text{\%} \end{gathered}[/tex]
