## Elementary Statistics (12th Edition)

The z-scores: Male: $z=\frac{value-mean}{standard \ deviation}=\frac{4.91-5.072}{0.395}=-0.41$. Female: $z=\frac{value-mean}{standard \ deviation}=\frac{4.32-4.577}{0.382}=-0.67$. The male's z-score is higher, therefore it has the higher count relative to the sample.
