Final answer:
The mean income for the population of twelve University Presidents is $294,500.
Step-by-step explanation:
The subject of this question is Mathematics and it is suitable for High School level.
To find the mean (average) income of the population of twelve University Presidents, you need to add up all the incomes and divide the sum by the total number of incomes.
So, the mean income can be calculated as:
Mean income = (Income1 + Income2 + ... + Income12) / 12
Plugging in the given values:
Mean income = ($464,000 + $285,000 + $207,000 + $553,000 + $196,000 + $285,000 + $266,000 + $447,000 + $556,000 + $285,000) / 12
Mean income = $3,534,000 / 12
Mean income = $294,500
Therefore, the mean income for the population of twelve University Presidents is $294,500.
