QuestionEstimate the mean age of females at first child birth using $f(x)=22 x^{0.045}$ for the years 2010, 2013, and 2019.

Studdy Solution
Calculate the mean age for the year201.
$$f(19) =22 \cdot19^{0.045} \approx23.46$$The mean age of females at the birth of a first child in the years2010,2013, and201 are approximately22.96,23.16, and23.46 years respectively.
