Total number of female workers= 262+159+120= 541
There are 120 workers with BMI above 30.
So, the proportion of workers with BMI above 30= (120/541)*100 =22.18%
So, yes. There are compelling evidence that more than 20% of individuals in the sampled population are obese.
-----------------------
With a single variable available it is not possible to run statistical analysis to check any hypothesis.
