Diagnostic test table

A test is used in 1,000 people: 100 truly have a condition. It detects 90 of them and is positive in 90 of the 900 without the condition.

  1. True positives=90.
  2. False positives=90.
  3. A positive result has 90/(90+90)=50% predictive value here.

What fraction of positive tests are true positives?
