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.
