A physical examination an audiometric test were given to 500 individuals with suspected hearing problems, of whom 300 were actually found to have hearing issues. The results of the examinations are presented in the following tables:

1. Compute the sensitivity and specificity of the findings shown for the physical examination and audiometric test. What type of questions would specify and sensitive address?

1. Compute the positive and negative predictive values of the findings shown for the physical examination and audiometric test. What type of questions would positive and negative predictive values address?

1. Compared with the physical examination, how would you characterize the audiometric test in terms of its specificity and sensitivity?

1. Compared with the physical examination, how would you characterize the audiometric test in terms of its positive and negative predictive values?
