Question

Many homeowners buy detectors to check for the invisible gas radon in their homes. How accurate are these detectors? To answer this question, university researchers placed 12 radon detectors in a chamber that exposed them to 105 picocuries per liter of radon. The detector readings were as follows: 91.9, 97.8, 111.4, 122.3, 105.4, 95.0, 103.8, 99.6, 96.6, 119.3, 104.8, 101.7 Is there convincing evidence that the mean reading of all detectors of this type differs from the true value of 105 picocuries per liter of radon? Carry out a test in detail (*you may assume any required conditions are met but give all other necessary information). State your conclusion.
