Acommon characterization of obese individuals is that their body mass index is at least 30 [bmi = weight/(height)2, where height is in meters and weight is in kilograms]. an article reported that in a sample of female workers, 265 had bmis of less than 25, 158 had bmis that were at least 25 but less than 30, and 123 had bmis exceeding 30. is there compelling evidence for concluding that more than 20% of the individuals in the sampled population are obese?
