Answer:
natural rate of unemployment 3.6%
labour force participation rate 69.7%
Step-by-step explanation:
![natural\ rate\ of\ unemployment = (no\ of\ unemployed)/(total\ labor\ force) * 100](https://img.qammunity.org/2020/formulas/business/high-school/optsfgaxncnfldbjvdwvnhjdzprqtfgvsx.png)
from the data given in the question we have
employed = 33.86 million = 33860000
unemployed = 1.27 million = 1270000
therefore we have natural rate of unemployment
![=(1270000)/(33860000) * 100 = 3.6%](https://img.qammunity.org/2020/formulas/business/high-school/h10k16ziqnq7okd11zce68kr3pc8ndhvl1.png)
labour force participation rate is calculated as
labour force participation rate
![= (labour\ force)/(adult\ population)](https://img.qammunity.org/2020/formulas/business/high-school/zprj2emcl1qbtzgxbzjdyt49draquqe078.png)
labor force = employed + unemployed labor = 33.86 +1.27 = 35.13 million
= 35130000 / 50400000 = 69.7%
