Answer:
B. 45
Step-by-step explanation:
We have been given a stem and leaf plot and we are asked to find the median age for our given plot.

22, 23, 29, 31, 34, 36, 38, 40, 43, 45, 47, 48, 49, 53, 57, 58, 62, 63, 65.
We can see that our data set has 19 data points, so median age will be:
We can see that 10th data point of our data set is 45, therefore, median age is 45 and option B is the correct choice.
