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 12 tombs in a particular region were measured in
becquerels per cubic meter Ba/m. For this data, assume that x= 3.651 Bq/m^3 and s= 1.197 Bq/m^3. Use this information to estimate, with 95% confidence, the true mean level of radon exposure in tombs in the region.
Interpret the resulting interval. Assume that the sampled population is approximately normal.
The confidence interval is ?
