01

Given Information

It is given in the question that,

02

Explanation

To find the unemployment rate for each level, divide the difference between 'in the labor force' and 'employed' by the 'in the labor force' from the data.

The unemployment rate for the people who didn't finish high school

=12470−1140812470=106212470=0.0852

The unemployment rate for people who did high school but not college

=37834-3585737834=197737834=0.0523

The unemployment rate for people who have less than a bachelor's degree

=34439-3297734439=146234439=0.0425

03

Explanation

The unemployment rate of people who are college graduates

=40390-3929340390=109740390=0.0272
