region were measured in becquerels per cubic meter (Bq/m³). For this data, assume that x = 3,704 Bq/m³ and s=1,178 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.

Question

what is The confidence interval ? Interpret the interval.

 
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 particu region were measured in becquerels per cubic meter (Bq/m³). For this data, assume that x = 3,704 Bq/m³ and s = 1,178 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.
