**Understanding Margin of Error in Poll Results**

A magazine reported results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 11% chose chocolate pie, and the margin of error was given as ±3 percentage points.

**What is meant by the statement "the margin of error was ±3 percentage points"?**

Choose the correct answer below:

- **A.** The statement indicates that the study is only 3% confident that the true population percentage of people that prefer chocolate pie is in the interval 1% – 3%.

- **B.** The statement indicates that the true population percentage of people that prefer chocolate pie is in the interval 1% – 3%.

- **C.** The statement indicates that the interval 1% – 3% is likely to contain the true population percentage of people that prefer chocolate pie.

- **D.** The statement indicates that the study is 100% – 3% = 97% confident that the true population percentage of people that prefer chocolate pie is 11%.

Expert Solution

Step 1

The margin of error is the amount of random sampling error in the results of a survey. The larger the margin of error, the less confidence one should have that a poll result would reflect the result of a survey of the entire population.

here, a magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents 115 chose the chocolate pie, and the margin of error was given as

\pm 3

percentage points.
