Question

The mean of 8
numbers is 26. What is the sum of all
observations? *
​

Answer 1

Answer:

Mean of eight observation = 26

Sum of eight observation = 216

     One more number is included

Sum of nine observation = 234

       The included number = sum of 9 observation - sum of 8 obsrevation

                                           = 234 - 216

                                           = 18  

Therefore ans = 18
