Problem

Scheduling requires a wait estimate within \(\pm~2~\text{minutes}\). The original wait is \(26~\text{minutes}\), but the report is \(20~\text{minutes}\). Calculate the absolute error, test it against the tolerance, judge the precision, and give a suitable report.

absolute error = |20−26|=6 minutes; tolerance test = 6≤2; precision = sufficient; suitable report = 20 minutes

absolute error = |30−26|=4 minutes; tolerance test = 4>2; precision = insufficient; suitable report = 30 minutes

absolute error = |20−26|=6 minutes; tolerance test = being in the twenties is treated as within ±2 minutes; precision = sufficient; suitable report = 20 minutes

absolute error = |20-26|=6 minutes; tolerance test = 6>2; precision = insufficient; suitable report = 26 minutes
