Ang z-score ng $0.18$ ay tumutugma sa isang lugar ng $0.57142$
$p (z < 0.18) = 0.57142$
Ang nakuhang peluang na $z < 0.18$ ay may $57.142 %$

2. Hanapin ang cumulative na probablidad ng mga halaga ng z-scores na mas mataas kaysa sa $0.18$

Upang makita ang pampamahaging katotohanan ng mga halagang mas mataas kaysa sa $0.18$ , kailangan nating ibawas ang pampamahaging katotohanan ng mga halaga na mas mababa kaysa sa $0.18$ mula sa kabuuang katotohanan sa ilalim ng kurba, na katumbas sa $1$ :

$1 - 0.57142 = 0.42858$
$p (- 0.18 > z > 0.18) = 0.42858$
Ang pampamahaging katotohanan ng $z > 0.18$ ay $42.858 %$

3. Hanapin ang cumulative na probablidad ng mga halaga ng z-scores hanggang sa $- 0.18$

Gamitin ang negatibong z-table upang mahanap ang halagang katugma ng $- 0.18$ . Ang halagang ito ang pampamahaging katotohanan ng lugar sa kaliwa ng $- 0.18$ .
