Answer:
Median = 18
Step-by-step explanation:
The median is the middle number if the elements (prices) are arranged from least to greatest.
let's arrange the prices of watches from least to greatest:
12, 15, 16, 16, 20, 22, 24 27
Since there are even number of numbers (8), the median is the value between 4th and 5th numbers.
4th number is 16
5th number is 20
We need the value between 16 and 20. We get that by adding these 2 and dividing by 2:
16 + 20 = 36
36/2 = 18
THus, median = 18
