The mean age at which women marry is 23.5 years with a standard deviation of 2.3 years. Find the relative positions for a man who marries at age 24 and a woman who marries at age 22.

\begin{aligned}\operatorname{Man} z & =\frac{X-\bar{X}}{s}=\frac{24-26.4}{2}=-1.2 \\\text { Woman } z & =\frac{X-\bar{X}}{s}=\frac{22-23.5}{2.3} \approx-0.65\end{aligned}

In this case, the woman’s age at marriage is relatively higher than the man’s age at marriage.
