Many ancient tombs were cut from limestone rock that contained uranium. Since most such tombs are not well-ventilated, they may contain radon gas. In one study, the radon levels in a sample of 1212 tombs in a particular region were measured in becquerels per cubic meter (Bq divided by m cubed )Bq/m3. For this data, assume that x overbarxequals=3 comma 4713,471 Bq divided by m cubedBq/m3 and sequals=1 comma 1601,160 Bq divided by m cubedBq/m3. Use this information to estimate, with 9595% confidence, the true mean level of radon exposure in tombs in the region. Interpret the resulting interval.
