Hi! I learnt how to find the p-value of a test, but I wasn't sure which type of distribution to use and how to calculate. Thank you!

Use the following for questions 2 and 3. A common characterization of obese individuals is that their body mass index (BMI) is at least 30. An article reported that in a sample of 541 female workers, 421 had BMIs of less than 30, and 120 had BMIs exceeding 30. A researcher wants to test whether there is compelling evidence for concluding that more than 20% of the individuals in the sampled population are obese. What is the p -value for this test? Give your answer to 3 decimal places
