Explanation

Given the following data

Re- arranging the data in an ascending order

We have the following data

20, 17, 4, 20, 19

The number of the data = 5

Mean = sum of the data / number of the data

Mean = 20 + 17 + 4 + 20 + 19 / 5

Sum of the data = 20 + 17 + 4 + 20 + 19

Sum of the data = 70

Mean = 70/5

Mean = 14
