We must find the margin of error for a poll with a sample size of n = 1550 people.
The margin of error with a 95% confidence level is given by the following equation:
[tex]error=\pm\frac{1}{\sqrt[]{n}}\cdot100[/tex]
in percentage.
Replacing the value n = 1550 in the equation above, we find that error is:
[tex]error=\pm\frac{1}{\sqrt[]{1550}}\cdot100\cong2.54[/tex]
in percentage.
Answer: 2.54%
