Answer:

17.9

Step-by-step explanation:

We have given a set of values.

12,13,15,16,19,19,19,20,21,25

We have to find mean of above values.

Mean is equal to the ratio of sum of all values to total number of values.

Mean = sum of values / number of values

Sum of values = 12+13+15+16+19+19+19+20+21+25

Sum of values = 179

Total number of values = 10

Hence,

Mean = 179 / 10

Mean = 17.9 which is the answer.
