In a poll with 40% support and a margin of error of +/-4, which range could be the true support?

Margin of error shows how far the true support could be from the poll’s estimate. With 40% and a margin of error of 4 percentage points, the true support could be between 36% and 44%. You get this by adding and subtracting: 40% ± 4% → 36% to 44%. The other ranges don’t fit because they lie outside that 36–44% interval or shrink it beyond what the margin allows.
