Question: A magazine provided results from a poll of adults who were asked to identify their favorite pie. among the ​respondents, ​% chose chocolate​ pie, and the margin of error was given as percentage points. describe what is meant by the statement that​ the margin of error was given as percentage​ points.

The statement that the margin of error was given as percentage points means that the true percentage of adults who chose chocolate pie could be higher or lower than the reported percentage by that amount. For example, if 25% chose chocolate pie and the margin of error was 3 percentage points, then the true percentage could be anywhere between 22% and 28%. The margin of error reflects the uncertainty that comes from using a sample to estimate a population parameter  .
