To find the median age, we first need to list all the ages in order:
28, 31, 32, 34, 42, 47, 49, 54
Since there are 8 ages listed, the median will be the average of the 4th and 5th ages.
In this case, the 4th age is 34 and the 5th age is 42.
So, the median age of the group of friends is 38 years old.
