Use sample data to estimate population means/proportions and develop margins of error using simulation.

Apply an explicitly informal interval-overlap rule

Problem

The displayed estimates are \(A~=~51\%~\pm~4~\text{points}\) and \(B~=~48\%~\pm~4~\text{points}\). Compute \(\text{both}~\text{intervals}\), find their gap or overlap, and apply the stated informal rule without claiming a formal significance test.
