3. Ultrasound can be used to diagnose acute appendicitis in patients fronting with abdominal pain. In positive diagnoses, the appendix is usually surgically removed as appendicitis can be potentially life threatening. However, an incorrect diagnosis can lead to the removal of a normal appendix although the body can function normally without one. (a) Create a binary classification table for the ultrasonic appendicitis test described in the information sheet. Assume a sample population of 1000 people fronting with abdominal pain. Ensure that you carefully explain the steps involved in creating the table.

Diagnosis of appendicitis:

Ultrasound can be used to identify cases of appendicitis. In a study of the use of the tech- nique [2], researchers were able to identify an overall sensitivity of 82% and a specificity of 54% of ultrasound testing across several clinics. This was amongst patients who fronted with abdominal pain, 72% who were later diagnosed with appendicitis through separate testing.
