In order to get the mean, we need to add up all the numbers and then divide by the number of numbers. The numbers given above are 90,000, 60,000, 70,000, 90,000 and 20,000. The total of the numbers is 330,000. To get the mean, divide 330,000 by 5 and we get 66,000. Therefore, the mean annual salary at the company is $66,000. Hope this helps!
