Answer
The male's z-score is higher, therefore it has a relatively higher BMI.
Work Step by Step
The z-scores: $z_{male}=\frac{value-mean}{standard \ deviation}=\frac{28-26.601}{5.359}=0.261$.
$z_{female}=\frac{value-mean}{standard \ deviation}=\frac{29-28.441}{7.394}=0.076$. The male's z-score is higher, therefore it has a relatively higher BMI.
