Solution:
We want to find the monthly difference in median income for a female with a diploma and some college versus a bachelor's degree.
From the table;
The earning of a female with a diploma and some college is given to be $717.
We read the data for some college.
The earnings for a female with a bachelor's degree is $1041.
Thus the monthly difference in median income is;
[tex]=4(weekly\text{ }difference)=4(1041-717)=1296\text{ dollars}[/tex]
