Since the results are projections, the accuracy depends
on how many people were asked. The more people that are randomly
asked, the better the accuracy of the projections.
Suppose a candidate is projected to get 48% of the votes,
and the polls results are accurate to within 4%.
This means the candidate should receive somewhere between 44%
(48% - 4%) and 52% (48% + 4%). Using a compound inequality
with x representing the percent of the vote received, we write
44 ≤ x ≤ 52. This means that x is somewhere between
44% and 52%. Will the candidate win? It is too close to know
at this time and we will have to wait until the election!!
