Amagazine provided results from a poll of 2000 adults who were asked to identify their favorite pie. among the 2000 respondents, 14% chose chocolate pie, and the margin of error was given as plus or minus5 percentage points. describe what is meant by the statement that "the margin of error was given as plus or minus5 percentage points".

9% - 19% is the estimated number of people liking the chocolate pie

Explanation:

The margin of error is an estimated number of percentage surrounding a guess. In a representative survey or a poll ( done in order to guess something about the whole population), there is always some uncertainty as only a limited number of people are asked to state their opinion.

The 14% in the above study is only an estimated number because only 2000 people were asked. Using a specific formula, the margin of error of plus minus 5% was established, it means that to be sure this poll is valid, one must add or subtract the 5%.
