The histograms show that the distributions are not normal, but similar to one another. The same with the box plot. There doesn’t seem to be an issue to run a t-test on these two groups.

The striations are not identical when looking at the respondent’s age when 1st child was born (stranger) by gender. The mean should be an appropriate measure of central tendency, and is lower in females, as seen in the box plot. However, because the distributions are similar enough, the t-test can still be run.
