[AI-generated answer — Bot GPT 3.5]

To find the median age, we first need to list all the ages in numerical order:

28, 31, 32, 34, 42, 47, 49, 54

Since there are 8 ages, the median will be the average of the 4th and 5th ages when listed in numerical order.

Therefore, the median age of the group of friends is (34 + 42) / 2 = 38 years.
