A common characterization of obese individuals is that their body mass index is at least 30 [BMI = weight/(height)?, where height is in meters and weight is in kilograms]. An article reported that in a sample of female workers, 262 had BMIS of less than 25, 159 had BMIS that were at least 25 but less than 30, and 122 had BMIS exceeding 30. s there compelling evidence for concluding that more than 20% of the individuals in the sampled population are obese? n USE SALT (a) State the appropriate hypotheses with a significance level of 0.05. O Ha: p = 0.20 H,:p> 0.20 O Ho: p > 0.20 H:p= 0.20 O Ho: p = 0.20 H:p< 0.20 O Hg: p = 0.20 H: p 0.20 Calculate the test statistic and determine the P-value.

There is sufficient evidence that more than 20% of the population of female workers is obese. O Reject the null hypothesis. There is not sufficient evidence that more than 20% of the population of female workers is obese. O Reject the null hypothesis.
