Use the next formula to find the z-score:

[tex]\begin{gathered} z=\frac{x-\mu}{\sigma} \\ \\ \mu:mean \\ \sigma:standard\text{ }deviation \end{gathered}[/tex][tex]\begin{gathered} z=\frac{14.3cm-17.4cm}{3.2cm} \\ \\ z=\frac{-3.1}{3.2}\approx-0.97 \end{gathered}[/tex]

Then, the z-score for the given situation i s
