Answer: a) Labor force participation rate = 72.46%, b) Unemployment rate = 1.8%.
Step-by-step explanation:
Since we have given that
Number of people who have at least a bachelor's degree = 71.9 millions
Number of people who were employed = 52.1 millions
Number of people who were unemployed = 1.3 millions
So, Labor- force participation rate would be
[tex]\dfrac{Employed}{Total}\times 100\\\\=\dfrac{52.1}{71.9}\times 100\\\\=72.46\%[/tex]
Unemployment rate for this group would be
[tex]\dfrac{Unemployed}{total}\times 100\\\\=\dfrac{1.3}{71.9}\times 100\\\\=1.8\%[/tex]
Hence, a) 72.46%, b) 1.8%.
