Report quantities with accuracy appropriate to measurement limitations.

Compare measurements using uncertainty intervals

Problem

A board’s measured length is \(15.2~\text{to}~15.5~\text{inches}\), and another board’s measured length is \(15.6~\text{to}~15.9~\text{inches}\). Are the measurements meaningfully different given their accuracy?
