  1. Given the following data:

Number of patients = 3,293

Number of patients who had a positive test result and had the disease = 2,184

Number of patients who had a negative test, and did not have the disease = 997

Number of patients who had a positive test result, but did not have the disease = 55

Number of patients who had a negative test result, but who had the disease = 57

  1. Create a complete and fully labelled 2x2 table (10)
  2. Calculate the positive predictive value (5)
  3. Calculate the negative predictive value (5)
  4. Calculate the likelihood ratio for a positive test result (5)
  5. Calculate the likelihood ratio for a negative test result (5)
