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 (Bq / m). For this data, assume that x = 3,688 Bq/ m° and s = 1,218 Bq/m. 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 ( D (Round to the nearest integer as needed.)
