To find the median age from the stem-and-leaf plot, first list all the ages in order:
28, 31, 32, 34, 42, 47, 49, 54
Since there are 8 ages, the median will be the average of the middle two ages when the ages are listed in order. In this case, the middle two ages are 34 and 42.
Therefore, the median age of the group of friends is (34 + 42) / 2 = 38 years old.
