Step-by-step explanation:
1. Given the information from the table, let's calculate the mean income for African Americans households of a certain country in 2008.
For a successful work, first of all we need to take the data from two columns : Midpoint Salary and Frequency (in thousands):
Mean income = (10,000 * 4,491) + (30,000 * 3.844) + (50,000 * 2,500) + (70,000 * 1,498) + (90,000 * 875) + (125,000 * 994) + (175,000 * 323) + (225,000 * 72)/ Sum of all the frequency (in thousands)
Mean income = (10,000 * 4,491) + (30,000 * 3.844) + (50,000 * 2,500) + (70,000 * 1,498) + (90,000 * 875) + (125,000 * 994) + (175,000 * 323) + (225,000 * 72)/ Sum of all the frequency (in thousands)
Mean income = 665'815,000/ 14,597
<u>Mean income = $ 45,613 (Rounded to the nearest dollar)</u>
