I'm having some troubles with some math.
In a class, there are 28 students.
They have done some research about, how much they earned a month.
The income is between €0 and €2500.
It looks like this:
[0; 500] (8 students)
]500; 1000] (6 students)
]1000; 1500] (1 student)
]1500; 2000] (4 students)
]2000; 2500] (9 students)
The numbers in the intervals indicates € the students have earned, and in parentheses, how many students that have earned it.
I need to find the average income for the students.
Help.
