Answer 2

The median age of Amelia's friends is the value separating the ages list into two halves, which is 14 years in this case.

Step-by-step explanation:

The median age is the value that separates the dataset into two equal halves. To find the median age from Amelia's data, we first need to list all ages in order according to their frequency. The dataset listed out will be: 11, 11, 11, 12, 12, 12, 12, 13, 13, 14, 14, 14, 14, 15, 15, 15, 15, 15, 16, 16. As there are 20 data points, the median will be the average of the 10th and 11th values in the ordered list, which are both 14 years. Therefore, the median age of Amelia's friends is 14 years.
