I did not understand how did you calculate the means of 55400. Before taking account Martin Gutenburg, the mean was 55000. But the Mr. G enter into the population, it becomes 55400. i caculate the amount of mean 94622. Please enlighten me!
The example is wrong, but not in the way you thought. Gutenburg’s salary should be $100 million per year.
That adds 100,000,000 to the total wage bill and 1 person to the number of people.
The mean salary is always:
the sum of (Number of people x their salary)/number of people.
Note that the amounts in the example are in 000s
