To find the median age, we first need to list all the ages in order:
28, 31, 32, 34, 42, 47, 49, 54
There are 8 ages in total, so the median age will be the average of the 4th and 5th ages when they are listed in order.
In this case, the 4th age is 34 and the 5th age is 42.
Median age = (34 + 42) / 2 = 38
Therefore, the median age of the group of friends is 38 years old.

To find the median age, we need to find the middle value in the list of ages. First, we need to put all the ages in order from smallest to largest:
21, 22, 24, 27, 29, 34, 42, 54
The median is the middle value, which in this case is 29 years old.
