years.
The median age is 32 years.
To find the median, arrange the ages in numerical order: 28, 31, 32, 34, 42, 47, 49, 54.
Since there are 8 ages, the median is the average of the 4th and 5th ages in the ordered list, which are 32 and 34.
(32 + 34)/2 = 66/2 = 32
Therefore, the median age is 32 years.
