Question

Answer 1

#Solution:

Margin of Error:-

The margin of error is a statistic expressing the amount of random sampling error in a survey's results.

In other words, margin of error expresses the maximum expected difference between the true value and the calculated value of any experiment (here election poll).

The larger the margin of error, the less confidence one should have that the poll's reported results are close to the true figures; that is, the figures for the whole population.

Margin of error tells us that how confidence the poll's results about the election.

As poll is based on a sample which is part of the whole population, so, there is,obvious some errors which should be mentioned with the poll's result.
