Ang z-score ng $- 0.132$ ay tumutugma sa isang lugar ng $0.44828$
$p (z < - 0.132) = 0.44828$
Ang nakuha peluang na $z < - 0.132$ ay $44.828 %$

3. Kalkulahin ang pangkabuuang probabilidad sa pagitan ng 0.198 at -0.132

Para mahanap ang cumulative probability ng lugar sa pagitan ng dalawang z-scores, ibawas ang mas maliit na cumulative probability (lahat sa kaliwa ng $- 0.132$ ) mula sa mas malaking cumulative probability (lahat sa kaliwa ng $0.198$ ):

$0.57926 - 0.44828 = 0.13098$
$p (- 0.132 < z < 0.198) = 0.13098$
Ang cumulative probability na $- 0.132 < z < 0.198$ ay $13.098 %$
