Problem R9.8

Radon detectors Radon is a colorless, odorless gas that is naturally released by rocks and soils and may concentrate in tightly closed houses. Because radon is slightly radioactive, there is some concern that it may be a health hazard. Radon detectors are sold to homeowners worried about this risk, but the detectors may be inaccurate. University researchers placed a random sample of 11 detectors in a chamber where they were exposed to 105 picocuries per liter of radon over 3 days. A graph of the radon readings from the 11 detectors shows no strong skewness or outliers. The Minitab output below shows the results of a one-sample t interval.Is there significant evidence at the 10% level that the mean reading M differs from the true value 105? Give appropriate evidence to support your answer. s Recognize paired data and use one-sample t procedures to perform significance tests for such data
