In the next election, 15,000 people will actually vote for Candidate A. A poll has a percent error of 4%. Which statement descri
salantis [7]

The poll has an error of 600 votes. The total number of votes including the error shown by the poll is 15600 or 14400.

Statement B is correct.

<h3>What is the percentage?</h3>

A percentage can be defined as a relative number that shows the hundredth part of the given number. The percentage is represented by the sign "%".

Given that In the next election, 15,000 people will actually vote for Candidate A. A poll has a percent error of 4%.

The error can be calculated as given below.

error = 15000 \times \dfrac {4}{100}

error = 600

The poll has an error of 600 votes. This will affect the total number of votes in the election.

The total number of votes V including errors are given as,

<em />

<em />V = 15000 +/- error

V = 15000 + 600 = 15600

or

V = 15000-600 = 14400

Hence we can conclude that the total number of votes including the error shown by the poll is 15600 or 14400. Statement B is correct.

To know more about the percentage, follow the link given below.
