Question

If different values of variable x are 19.8, 15-4, 137, 1171, 11-8, 126, 12-8, 18-6, 20.5 and 21-1, find the mean. ​

Answer 1

Answer:

Step-by-step explanation:

Solution

The given values are 19.8,15.4,13.7,11.71,11.8,12.6,12.8,18.6,20.5  and 21.1

We know that n =10

So Mean =(19.8+15.4+13.7+11.71+11.8+12.6+12.8+18.6+20.5+21.1)/10

By further calculation

=158.01/10

=15.801
