Answer:
Therefore, the survey's margin of error is ±3%
Explanation:
From a survey, a reporter determined that true estimate for the proportion of citizens who plan to sign a petition is between 68% and 74%.
given estimate range = 68% to 74%
Margin of error = (74% - 68%) ÷ 2
6 ÷ 2 = 3%
Therefore, the survey's margin of error is ±3%
