The question is incomplete, here is the complete question I came across earlier;
Benjamin owns a small Internet
business. Besides himself, he employs nine other people. The salaries earned by
the employees are given below in thousands of dollars (Benjamin's salary is the
largest, of course). 25, 27, 40, 50, 36, 50, 42, 65, 75, 30. Determine the mean
for salary?
The answer is "44".
The mean for salary which is generally called the average,
is the number you get by including all salaries together, at then dividing by
the quantity of them. Another term median is where half acquire all more, half
gain less.
25+27+40+50+36+50+42+65+75+30 = 440
Total number of salaries = 10
440/10 = 44 is the answer.
