- Many Ancient Tombs Were Cut From Limestone Rock That Contained Uranium Since Most Such Tombs Are Not Well Ventilated T 1 (69.86 KiB) Viewed 30 times
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/m³). For this data, assume that x = 3,609 Bq/m³ and s = 1,206 Bq/m³. 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 (Round to the nearest integer as needed.)
